20 how I kept back nothing that was helpful, but proclaimed it to you, and taught you publicly and from house to house, 21 testifying to Jews, and also to Greeks, repentance toward God and faith toward our Lord Jesus Christ. (Acts 20:20–21, NKJV)
Faith toward our Lord Jesus Christ will not exist in a person’s life until that person repents toward God. Repentance is changing the mind toward its object (in this case, toward God). It is about thinking differently, and then we live differently. Repentance is not the regret of feeling sorry toward God. Genuine repentance results from godly sorrow over sin (2 Cor. 7:9-10). Some think to repent means “to turn,” but this is also incorrect. Only when we think differently about God and our sin against Him will we turn to God for salvation. Paul shows the difference between repentance and turning to God in Acts 26:20 when he explained he preached the gospel to people so “that they should repent, turn to God, and do works befitting repentance.” Paul did not say, “turn (repent), and turn to God.” He said to repent (change your mind) and turn to God. Repentance, produced by godly sorrow, bears the fruit of turning to God (that is, “works befitting repentance,” cf. Lk. 3:7-14). The gospel requires repentance 1) Toward God, Acts 20:21; 2) Of sins, Lk. 5:32; 13:3, 5; Acts 8:22; 3) For the remission of sins, Acts 2:38; 3:19; and 4) Because God commands it, Acts 17:30. Without repentance, we will not escape the condemnation our sins bring from God (Rom. 2:3-5).
The Lord has sworn in truth to David; He will not turn from it: “I will set upon your throne the fruit of your body.” (Psalm 132:11, NKJV)
God’s promise to David, while initially kept by the ascension of Solomon to the throne, had a much grander objective (2 Sam. 7:12-13; 1 Chron. 22:9-10; 28:5-6). The Davidic promise of a king from the fruit of his body was fulfilled in the coronation of Jesus. The angel Gabriel announced that God would give Mary’s child “the throne of His father David” (Lk. 1:32). On Pentecost, the apostle Peter proclaimed God had indeed fulfilled His promise to David by the resurrection of Jesus and His ascension to the right hand of God (Acts 2:30-36; Psa. 110:1-2). Later, James (the brother of Jesus) said God had rebuilt the ruling monarchy of the house of David, which Amos predicted (Acts 15:13-19; Amos 9:11-12). The kingdom over which the son of David reigns today is the church, composed of all who come to Jesus Christ in faith through His gospel (Matt. 16:18-19; Rom. 1:16-17; Col. 1:13-14). God keeps His word – always. King Jesus reigns today over a kingdom that is enduring, unshaken by “every wind of doctrine” and the “trickery of men” (Heb. 12:28; Eph. 4:14). Salvation is in Christ’s kingdom (Acts 2:30-41, 47). Christ’s kingdom was promised by God, prophesied by His prophets, and proclaimed by the gospel. It fills the whole earth, and it “shall never be destroyed” (Dan. 2:34-35, 44; Mk. 1:14-15; 9:1; Acts 1:8; 2:1-4, 36-41, 47). The pressing question is, are you a citizen of His kingdom (Col. 1:13; Acts 2:37-38, 47)?
8 To me, who am less than the least of all the saints, this grace was given, that I should preach among the Gentiles the unsearchable riches of Christ, 9 and to make all see what is the fellowship of the mystery, which from the beginning of the ages has been hidden in God who created all things through Jesus Christ; 10 to the intent that now the manifold wisdom of God might be made known by the church to the principalities and powers in the heavenly places, 11 according to the eternal purpose which He accomplished in Christ Jesus our Lord, 12 in whom we have boldness and access with confidence through faith in Him. (Ephesians 3:8–12, NKJV)
The gospel Paul preached reveals the “unsearchable riches of Christ” for all the world to see. In it, salvation from sin is available to all “by grace…through faith” (v. 8; Eph. 2:8). The gospel Paul preached reveals God’s purposes for the redemption of sinners in Christ (v. 9). The gospel Paul preached reveals the importance of the church (v. 10-11). First, because “by the church,” God’s many-sided wisdom is made known to the unseen realms (v. 10; 1 Pet. 1:10-12). Second, because it is crucial to God’s “eternal purpose” fulfilled in Christ (v. 11). The church is not an afterthought of God. The gospel Paul preached reveals our bold and confident access through faith in Christ into every spiritual blessing of God (v. 12, Eph. 1:3). The gospel is truly the wisdom and power of God (1 Cor. 1:24). The church (the redeemed) is the product of the gospel (Acts 2:47). The church is important to God. It must be important to us.
4 Then the word of the Lord came to me, saying: 5 “Before I formed you in the womb I knew you; Before you were born I sanctified you; I ordained you a prophet to the nations.” (Jeremiah 1:4–5, NKJV)
Jeremiah was unique before his birth. (The unborn baby is new human life, not merely a blob of tissue connected to a woman.) The Bible repeatedly upholds the dignity of life as from God, formed and sustained by Him. In Eden, sin interrupted life and brought death. God’s plan to redeem sinners (us) from death would involve the death of His Son. But, His power of life over death would resurrect Jesus (Rom. 1:4). God chose Jeremiah before He formed Him. He set him in place as a prophet of God’s redemptive purposes. He would speak God’s word to a Judah, a sinful nation on the verge of destruction for her sins (Jer. 1:6-10). Judgment was coming, but divine mercy and redemption would also come (Jer. 21:1-10; 23:1-8). After God’s judgment against Judah (the seventy-year Babylonian exile), God would restore a remnant to the land (which occurred under Cyrus, King of Persia, Jer. 29:10-14; 25:11-12; Ezra 1:1-4). God would send “David” (Messiah) to be their King, vastly different from the kings who rebelled against God (Jer. 22). He would be “a Branch of righteousness” who would “reign and prosper” God’s people with salvation and safety (Jer. 23:1-8; 30:8-9). Messiah indeed came, but they killed Him. Yet, Jeremiah’s prophecy came true – Jesus now reigns over His kingdom at God’s right hand – “The Lord Our Righteousness” (Jer. 23:5-6; Acts 2:30-36; Heb. 1:8-9). Believe and obey the King and share in the salvation Jeremiah anticipated (1 Pet. 1:10-12; Acts 2:36-41).
1 Moreover, brethren, I declare to you the gospel which I preached to you, which also you received and in which you stand, 2 by which also you are saved, if you hold fast that word which I preached to you—unless you believed in vain.” (1 Corinthians 15:1–2, NKJV)
The gospel is God’s power to save the lost (Rom. 1:16). No other message has such power. Since all have sinned, every one of us needs its power to save us from sin, and the eternal death sin brings (Rom. 3:23; 6:23). To grasp the preeminence of the gospel message and its impact on our lives, the apostle certifies its pertinent features in today’s text. 1) The gospel is preached. It is a constant and fixed message, unchanged by the whims and foibles of men (1 Cor. 1:18-25). 2) The gospel is received. Believers do not keep it at arm’s length; they embrace it and thoroughly associate themselves with its converting power (Rom. 12:2). 3) We are to stand in the gospel. It is not a one-off message to be initially believed and then laid aside. We must continue in it, living by its guidance and truth (Col. 2:6-7). 4) The gospel saves us if we hold it fast. The gospel teaches us to keep on living by the gospel, holding to it as the pattern for our lives (Acts 2:42; 2 Thess. 2:15). The word “if” in verse two is huge. If we do not hold fast the word of the gospel, our faith is vain, idle, and useless. Yes, if we choose not to be faithful to the gospel, our faith fails, and we are lost – not because the gospel is weak or powerless, but because we cast it aside for sin. Believe and faithfully follow the gospel, and its power will save you.
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.
22 The Lord possessed me at the beginning of His way, before His works of old. 23 I have been established from everlasting, from the beginning, before there was ever an earth. (Proverbs 8:22–23, NKJV)
Wisdom cries out for us to receive her guidance of truth and understanding (Prov. 8:1-11). Not only does she “dwell with prudence,” Jehovah has possessed her from eternity past. 1) Wisdom attended God’s creation of the heavens and the earth (Gen. 1:1). She served as His “ready craftsman” when He fashioned the earth (Prov. 8:30, 24-31). The wonders of the heavens and the earth defy human intellect, power, skill, precision, and imagination. Divine wisdom, though invisible, is perceived by the things God has made (Rom. 1:20). 2) Wisdom attended God’s plan of human redemption. God made redemption in Christ “abound toward us in all wisdom and prudence” (Eph. 1:7-8). The church (those redeemed by the blood of Christ) reveals the “manifold wisdom of God” to heaven and earth (Eph. 3:10-11). 3) Wisdom attended God’s revelation of the gospel. The gospel is the “wisdom of God” that reveals His mind to the whole world (1 Cor. 2:6-13; Mk. 16:15). The gospel plums the depths of divine wisdom as it calls sinners to salvation (1 Cor. 1:18-25; Mk. 16:16). The wisdom of men pales in comparison to the wisdom that God possesses and has revealed in His word. Let us choose “the wisdom that is from above,” and bear the fruit of righteousness (Jas. 3:17-18).
