31 And the Lord said, “Simon, Simon! Indeed, Satan has asked for you, that he may sift you as wheat. 32 But I have prayed for you, that your faith should not fail; and when you have returned to Me, strengthen your brethren.” 33 But he said to Him, “Lord, I am ready to go with You, both to prison and to death.” 34 Then He said, “I tell you, Peter, the rooster shall not crow this day before you will deny three times that you know Me” (Luke 22:31–34, NKJV).
Peter, the stone, would soon crack under temptation, although he was sure he would never deny Jesus (Luke 22:54-62). Peter’s sin was grievous, but it would not define him. Jesus looked beyond Peter’s transgression to a future faith that would bless others. Indeed, Peter returned to Christ and, as an apostle, strengthened his fellow apostles and countless others. We can see ourselves in Peter. Satan wants to sift us as wheat like he tried to destroy Peter’s faith. When we yield to temptation in times of weakness, we have a friend in Jesus, an Advocate with the Father who intercedes for us when we confess our sins (1 John 1:9-2:2). Do not let your moment of weakness and sin define your faith. Like Peter, return to the Lord with godly sorrow and repentance (Luke 22:62; Acts 8:22-24). With revived faith, be a blessing to others. What a friend we have in Jesus! He will never leave or forsake us (Heb. 13:5-6).
17 You therefore, beloved, since you know this beforehand, beware lest you also fall from your own steadfastness, being led away with the error of the wicked; 18 but grow in the grace and knowledge of our Lord and Savior Jesus Christ. To Him be the glory both now and forever. Amen (2 Peter 3:17–18, NKJV).
It is essential to see the interdependent relationship between grace and knowledge in today’s passage. Peter’s summary draws attention to the truth his audience already knew (“since you know this beforehand,” v. 17) and warns against falling from their steadfast faith, led away by the error of the lawless. Growing in the “grace and knowledge of our Lord” protects us from being led away by error from the Lord (v. 18). Yes, God’s grace is greater than sin. But we cannot “continue in sin that grace may abound” (Rom. 5:20-6:1). (Grace is not a license to sin by teaching and following error.) Growing in grace is explained in Titus 2:11-14 as denying sin and living “soberly, righteously, and godly in the present age.” So, growing in grace requires us to increase in our knowledge of “the gospel of the grace of God” (Acts 20:24). Good fruit results when we hear, know, and follow “the grace of God in truth” (Col. 1:5-6, 9-11). The gospel is “the word of His grace” that strengthens us and grants us our eternal inheritance (Acts 20:32). Therefore, we are strengthened by God’s grace as we grow in our knowledge of His word (2 Tim. 2:1-2). Grace and knowledge are not opponents. They work together, bringing glory to our Lord and Savior Jesus Christ as they equip us to share in His glory (Col. 3:4).
28 And Peter answered Him and said, “Lord, if it is You, command me to come to You on the water.” 29 So He said, “Come.” And when Peter had come down out of the boat, he walked on the water to go to Jesus. 30 But when he saw that the wind was boisterous, he was afraid; and beginning to sink he cried out, saying, “Lord, save me” (Matthew 14:28–30, NKJV)!
Scripture says Christ’s disciples were fearful when they saw Jesus walking on the sea toward them (Matt. 14:24-26). Jesus reassured them with, “Be of good cheer! It is I; do not be afraid” (Matt. 14:27). Peter’s decision to walk out to Jesus was rooted in his trust in Jesus; he believed His word (“come”) and his power to make it happen. Peter’s decision certainly was not due to his ability to walk on water! Fear reappeared when Peter looked around and lost focus on Jesus. Will we admit that sounds very much like us at times? Sin and the storms of life shake us. Jesus is near, coming to offer relief, but we are afraid. He says, “Come to Me…and I will give you rest” (Matt. 11:28). And so, we begin to do just that, becoming a Christian and following Him. But our focus is easily diverted by the turmoil and trials of life; we become afraid, stop walking by faith, and begin to sink in the overwhelming flood of desperation, depression, and despair. Still, Jesus is ready and able to save us if we will call on Him, confessing our sins and repenting of them (Acts 8:22-24; 1 John 1:9). Living by faith means walking with Jesus through frightful moments, not just safe ones. He will not fail you. Jesus replaces fear with salvation’s abiding peace (Heb. 13:5-6).
9 Now as they came down from the mountain, He commanded them that they should tell no one the things they had seen, till the Son of Man had risen from the dead. 10 So they kept this word to themselves, questioning what the rising from the dead meant (Mark 9:9–10, NKJV).
Peter, James, and John had just witnessed the transfiguration of Jesus, seen Moses and Elijah talking with Him, and heard the Father’s voice say, “This is my beloved Son. Hear Him” (Mark 9:1-7). Why did Jesus tell them to tell no one what they had seen until “the Son of Man had risen from the dead?” Here are a couple of reasons. First, several were already bearing testimony that Jesus is the Son of God: (1) John the Baptist, the Elijah of prophecy (Mark 10:11-13; Matt. 11:14; John 5:33-35); (2) The Father Himself by the miracles of Jesus (John 5:36-37); and (3) The Scriptures (John 5:38-39). Second, the apostles were not yet prepared to tell others what they had seen. That was not their job at this moment. They still had much to learn from the Master. Only now did they understand John was the prophesied Elijah (Matt. 17:12-13). They did not know Jesus would rise from the dead (Mark 9:10). They did not yet grasp the redemptive work of Christ (Peter even rebuked Jesus for saying He would suffer, be killed, and rise after three days, Matt. 16:21-23). Rest assured, the apostles would tell others about the transfiguration when Christ commissioned them to preach the gospel to the world (Mark 16:15; Acts 1:8; see 2 Pet. 1:16-18). What can we learn from this? (1) Teachers must first be students of God’s word (1 Tim. 4:13, 15-16). (2) Teach what you know while maturing in your knowledge of God’s word (2 Tim. 2:15; Heb. 5:11-6:3). (3) Zeal without knowledge can be dangerous (Rom. 10:2-3).
4 When He had stopped speaking, He said to Simon, “Launch out into the deep and let down your nets for a catch.” 5 But Simon answered and said to Him, “Master, we have toiled all night and caught nothing; nevertheless at Your word I will let down the net.” 6 And when they had done this, they caught a great number of fish, and their net was breaking. (Luke 5:4–6, NKJV)
How would you react if you were a fisherman and a carpenter told you where and how to catch fish? Many would disregard such counsel as ignorant, presumptuous arrogance. But Peter did not react that way. The one advising Peter (the fisherman) had already gained the multitude’s interest by His miracles and His teachings (Lk. 4:40-44; 5:1). Indeed, Jesus had previously healed Peter’s mother-in-law of a high fever (Lk. 4:38-39). Peter’s humble faith in the word of Jesus is our lesson today. Our experience, our knowledge, our labor, our frustrations – none of these rise above the power and authority of Christ’s words (v. 5). Spiritual blessings result when we divest ourselves of every obstacle of our stubborn will and obediently yield to the word of Christ (v. 6). What if Peter had said, “I will, but I must rest first,” or “I will do that tomorrow when the conditions are more favorable,” or, “I don’t feel that will do any good?” The excuses used to resist the gospel of Christ are many (Acts 24:25). Instead of making excuses for not following the word of Christ, trust His word is the truth. “Launch out into the deep” (v. 4). He will bless you for obeying Him (Matt. 11:28-30). Jesus says to believe and obey His gospel, and He will save you (Matt. 7:21; Mk. 16:15-16).
27 But immediately Jesus spoke to them, saying, “Be of good cheer! It is I; do not be afraid.” 28 And Peter answered Him and said, “Lord, if it is You, command me to come to You on the water.” 29 So He said, “Come.” And when Peter had come down out of the boat, he walked on the water to go to Jesus. (Matthew 14:27–29, NKJV)
Would we have faith to step out of the boat? Peter did. He heard the Lord’s command to “come,” and he trusted Jesus. To “be of good cheer” means to be confident instead of fearful. Faith is in a struggle with fear. When we “step out of the boat” (as it were), we are replacing fear with trust and confidence in the word and power of Jesus. If Peter put his faith in himself when he stepped out of the boat, he would sink. When we trust in ourselves instead of the Savior, we also sink. Christians confidently “walk by faith, not by sight” (2 Cor. 5:7, 8). So, when Jesus says, “Do not be anxious about your life,” do we “step out of the boat” and trust God’s provisions (Matt. 6:25)? When He says, “If anyone desires to come after Me, let him deny himself, and take up his cross daily, and follow Me,” do we “step out of the boat” and confidently sacrifice ourselves for Christ (Lk. 9:23)? When He says, “He who loves father and mother more than Me is not worthy of Me. And he who loves son or daughter more than Me is not worthy of Me,” do we “step out of the boat” to love Jesus more than those most precious to us (Matt. 10:37)? Confidently do what Jesus commands. When you do, faith overcomes fear and seizes the spiritual victory in Christ (1 Jno. 5:4-5).
28 Then he said to them, “You know how unlawful it is for a Jewish man to keep company with or go to one of another nation. But God has shown me that I should not call any man common or unclean. 29 Therefore I came without objection as soon as I was sent for. (Acts 10:28–29, NKJV)
God separated Israel from the nations and codified that distinction in the law of Moses (Exo. 19:5-6; Deut. 7:1-11). That “middle wall of separation” was broken down in Christ (Eph. 2:14). God taught Peter the nations (Gentiles) were included in His redemptive plan by a dramatic vision. Clean and unclean animals were lowered in a sheet from heaven, and a voice told Peter, “Rise, Peter; kill and eat” (Acts 10:9-17). Peter drew the necessary conclusion not to call people “common or unclean.” That truth should permeate our thinking, words, and our treatment of others. Here are some lessons to ponder and apply. 1) The gospel is for all. Sin has defiled all of us (Rom. 3:23). Everyone needs sin’s stain cleansed by Christ (Rom. 1:16; Acts 22:16). Let us share the gospel so others may believe and turn to the Lord (Acts 11:21). 2) Prejudice has no place in the heart and life of Christians. God looks at the heart, not the outward appearance (skin color, ethnicity, gender, culture, caste, etc.) (1 Sam. 16:7). Grievous errors in judgment happen when based on appearance (Jno. 7:24; Prov. 18:13). 3) Obey God without objection (v. 29). When God has spoken, we listen and obey without resistance and complaint (1 Sam. 3:10). Christians must not murmur against the Lord’s will like Israel did in the wilderness (1 Cor. 10:10). Peter’s example of learning and obeying God’s will continues to encourage us.
Therefore those who were scattered went everywhere preaching the word. (Acts 8:4, NKJV)
Acts 8 is a chapter about preaching the gospel. Those who preached in this chapter were the persecuted, scattered saints (8:4), Philip the evangelist (8:5, 35, 40), and the apostles Peter and John (8:25). The message they preached was “the word” (8:4), “Christ” (8:5), things concerning the kingdom, the name of Jesus Christ, and baptism (8:12), “the word of the Lord” (8:25), “the gospel” (8:25), and “Jesus” (8:35). The result of their preaching was the conversion and salvation of souls. People believed and were baptized, and by doing so, they “received the word of God” (8:12-14). A sinning Christian learned from hearing the apostle’s teaching that he needed to repent and pray for God’s forgiveness (8:18-24). A lost Ethiopian came to believe in Jesus Christ and was baptized, resulting in great joy (8:35-39). One cannot read Acts 8 without being impressed with gospel preaching’s central role in saving sinners. The Samaritans, Simon, and the Ethiopian eunuch were brought to faith, obedience, and salvation from sins through preaching the gospel of Jesus Christ. Sinners cannot hear the word of God, believe it, call on the name of the Lord, and be saved without gospel preaching (Rom. 10:13-17). Why and what are you preaching, preacher? What kind of preaching do you want, Christian? Gospel preaching is not entertainment. It is not a psychology session. It is not the pleasing pabulum of positive platitudes. It is not a sharing session of opinions. It is the proclamation of the gospel, God’s power to save the lost (Rom. 1:16; Gal. 1:6-12; 2 Tim. 4:1-5). We need more gospel preaching, not less.
21 Then Peter came to Him and said, “Lord, how often shall my brother sin against me, and I forgive him? Up to seven times?” 22 Jesus said to him, “I do not say to you, up to seven times, but up to seventy times seven.” (Matthew 18:21–22, NKJV)
Repeatedly forgiving one who has sinned against us is not easy. It requires faith to do as Jesus said (limitless forgiveness). He went on to describe God’s forgiveness is driven by compassion, not withheld due to wearisome repetition. Such unceasing forgiveness means our hearts must be filled with the love, mercy, and longsuffering of God (see Sword Tips #2116 on 1 Timothy 1:15-16). It requires a generous, sympathetic heart toward the sinner and the struggles against sin to repeatedly forgive when wronged. Oh, the magnitude of God’s repeated forgiveness of us and our sins against Him! As God forgives us, we are to forgive others (Matt. 6:12, 14-15; 18:32-35). The numbers Peter proposed were literal. He thought seven was a perfectly generous amount of times to forgive repeat offenders. Jesus used numbers figuratively (“seventy times seven” does not make the four hundred ninety-first sin beyond our need to forgive). In another place Jesus said, “And if he sins against you seven times in a day, and seven times in a day returns to you, saying, ‘I repent,’ you shall forgive him” (Lk. 17:4). Ready, willing, abundant forgiveness is our task of faith when sinned against. We want and need God’s unending compassion and forgiveness (Matt. 18:23-27). Let us not withhold the same from those who sin against us (Matt. 18:28-35).
36 “Therefore let all the house of Israel know assuredly that God has made this Jesus, whom you crucified, both Lord and Christ.” 37 Now when they heard this, they were cut to the heart, and said to Peter and the rest of the apostles, “Men and brethren, what shall we do?” (Acts 2:36–37, NKJV)
When convicted that Jesus is Lord and Christ, sinners were cut to the heart for their sins against Him. Their urgent question was, “What shall we do?” The answer Peter gave was clear: Repent and be baptized (Acts 2:38). Today, people give different answers to the same question. Some say, “You can’t do anything – God must do everything for you to be saved.” That is not what Peter said. Some say, “Believe and pray the sinner’s prayer, and you will be saved.” That is not what Peter said. Some say, “God has already elected who will be saved and who will be lost, so whatever you do will not change your fate.” That is not what Peter said. Some say, “Plead for Holy Spirit baptism in addition to being baptized in water so you can be fully sanctified.” That is not what Peter said. Why not just do what Peter said? About three thousand believers were saved that day when they repented and were baptized (Acts 2:40-41). The way to be saved by Christ has not changed. The need for salvation is the same. The answer to the question, “What shall we do?” is the same. This is gospel salvation. Believe it. Obey it. Be saved by Christ.
