5 Now the purpose of the commandment is love from a pure heart, from a good conscience, and from sincere faith, 6 from which some, having strayed, have turned aside to idle talk, 7 desiring to be teachers of the law, understanding neither what they say nor the things which they affirm. (1 Timothy 1:5–7, NKJV)
To faithfully teach the gospel one must first be willing to be taught (see 2 Timothy 2:2). Commitment to the commands of God produce love from a pure heart, a good conscience and sincere faith. Love for God, for truth, and for others compels us to learn God’s word before trying to teach it. Desire to teach the gospel without having a knowledge of it may well result in leading a person astray from the very truth he desires to teach. Like zeal without knowledge, desire to teach that is not fettered to knowing the truth produces vain, yet confidently asserted babbling, instead of “godly edification which is in faith” (1 Timothy 1:4). Take time to study and learn God’s word. Examine your motive for desiring to be a teacher of the word. Is it “love from a pure heart, from a good conscience, and from sincere faith?” And remember, faithful teachers never stop studying to learn and know the truth they teach.
And those who are Christ’s have crucified the flesh with its passions and desires. (Galatians 5:24, NKJV)
The apostle has contrasted walking in the Spirit with fulfilling the lusts of the flesh (Galatians 5:16-17). He has pointed out the kind of life the flesh prompts men to pursue (the works of the flesh), with its fatal result (“those who practice such things will not inherit the kingdom of heaven,” Galatians 5:19-21). The character and conduct formed by the Spirit’s instruction and guidance is fruitful and robust, free from law’s condemnation (Galatians 5:22-23). Those who belong to Christ extinguish the flesh as the controlling factor of their lives (Galatians 2:20). Christians deliberately and methodically eliminate the influences and cravings of the flesh, so the fruit of the Spirit can thrive in their hearts and lives (Colossians 3:5). It is no accident that Christians bear the fruit of the Spirit. Through repentance, the heart has been conditioned to serve a new Master, Christ Jesus. The heart that is humble, repentant and responsive to the gospel is the perfect soil for bearing the fruit of the Spirit (Luke 8:15).
9 “The heart is deceitful above all things, and desperately wicked; Who can know it? 10 I, the Lord, search the heart, I test the mind, even to give every man according to his ways, according to the fruit of his doings. (Jeremiah 17:9–10, NKJV)
Now we are told why trusting in man brings the curse raised in Jeremiah 17:5-6. The heart is open to being deceived. It is where wickedness begins, and where it is housed. Jesus explained that sin comes from within us, from our hearts, and defiles us (Mark 7:20-23). The heart of which the Scriptures speak is not your blood pump, it is composed of your intellect, your will, your emotions, and your conscience. God knows the heart of every person, and He will render to every person “according to his ways.” Since our conduct proceeds from our heart, God’s judgment of us will be according to what we do (our ways, our doings). God does not say, “You have sinned, but your heart is good, therefore, everything is all right.” Instead, God says to “get yourselves a new heart and a new spirit,” that follows His will, and not your own (Ezekiel 18:31-32). Turn your heart away from sin and do God’s will. Then, both your heart and your life will be blessed by the Lord.
So, as much as is in me, I am ready to preach the gospel to you who are in Rome also. (Romans 1:15, NKJV)
Paul was eager to preach the gospel to the Christians in Rome. Not every Christian is a gospel preacher, like Paul (2 Timothy 1:11). But, every Christian must “always be ready to give a defense to everyone who asks you a reason for the hope that is in you, with meekness and fear” (1 Peter 3:15). To do that, the apostle Peter said we must sanctify (set apart) in our hearts Christ as Lord. We must recognize Christ as our supreme authority. His word rules us. He is the one to whom we submit our hearts and our lives. His word sustains our hope in Him. His word supplies the reasons we give in defense of our hope. So, we be learning and living the gospel (Hebrews 5:12-14). What we preach with our words and by our lives, shows whether we have set apart Jesus Christ in our hearts as Lord. Be sure Jesus rules in your heart. His word must prevail over everything you think and do. Proclaim His gospel with your words and by your actions. Otherwise, you have not yet sanctified Him in your heart as Lord. As such, you are unprepared to preach the gospel to others.
37 But although He had done so many signs before them, they did not believe in Him, 38 that the word of Isaiah the prophet might be fulfilled, which he spoke: “Lord, who has believed our report? And to whom has the arm of the Lord been revealed?” (John 12:37–38, NKJV)
The powerful arm of the Lord was revealed to Israel by the many signs (miracles) Jesus did before the people. His miracles were heaven’s testimony that He is the Christ, the Son of God (John 5:36; 20:30-31; Acts 2:22). Yet, despite His marvelous works, they did not believe in Him. Why not? John answers that question with another quote from Isaiah: “He has blinded their eyes and hardened their hearts, lest they should see with their eyes, lest they should understand with their hearts and turn, so that I should heal them” (John 12:40; Isaiah 6:9-10). It has been said there are none so blind as he who will not see. When we willfully harden our hearts against God and His Son, His testimony of truth will not penetrate it. We will remain lost in our unbelief. The strength of the Lord (His “arm”) has been revealed to the world through Jesus Christ. We must humble our hearts and open our eyes and ears to God’s powerful truth. By doing so, we can understand His will, turn back to God, and be healed of our sins.
23 Now when He was in Jerusalem at the Passover, during the feast, many believed in His name when they saw the signs which He did. 24 But Jesus did not commit Himself to them, because He knew all men, 25 and had no need that anyone should testify of man, for He knew what was in man. (John 2:23–25, NKJV)
The miracles of Jesus were signs to the people that He is from God. When they saw the signs He did, they believed in His name, or power. Without those miracles, there would have been no ability to know who Jesus was, or the power by which He spoke. By contrast, Jesus did not need signs to tell Him what was in the hearts of men and women. People did not need signs to confirm to Jesus who they were and what was in them. Being the Son of God, He knows the hearts of men. For example, He knew Nathaniel was an Israelite “in whom is no deceit” (John 1:47). He knows what is in your heart and mine (Hebrews 4:13). Let us be sure to entrust our souls to Him by faithfully honoring and obeying His authority as the Son of God.
16 Thus says the Lord of hosts: “Do not listen to the words of the prophets who prophesy to you. They make you worthless; They speak a vision of their own heart, not from the mouth of the Lord. 17 They continually say to those who despise Me, ‘The Lord has said, “You shall have peace”’; And to everyone who walks according to the dictates of his own heart, they say, ‘No evil shall come upon you.’” (Jeremiah 23:16–17, NKJV)
The false prophets in Jerusalem during the life of Jeremiah sound much like the false preachers today, who tell people such things as, “Let your conscience be your guide,” and, “join the church of your choice,” and, “God will accept every person who has a sincere heart” (that was the very falsehood for which God punished His people, verse 17). Living “according to the dictates of his own heart” brings a person under God’s wrath, not God’s approval and pleasure. Such worthless teaching made the people spiritually worthless (verse 16). When Jeremiah opposed these false prophets, they tried to have him killed (Jeremiah 26:4-14). A person who tells you God’s truth is not your enemy; don’t make him out to be one (Galatians 4:16). Speaking God’s truth has never been popular. But, we must speak truth, attempt to save souls and please God. We dare not speak error to please men, for by doing so, we lose our souls, and they remain lost, too (Galatians 1:10; 4:16; 1 Timothy 4:16).
