Example (good or bad)
1. Be a godly example for others to follow.
1 Tim. 4:12. Let no one despise your youth, but be an example to the believers in word, in conduct, in love, in spirit, in faith, in purity.
2. Pastors and elders are to be good examples for the flock.
1 Peter 5:2–4. Shepherd the flock of God which is among you, serving as overseers, not by compulsion but willingly, not for dishonest gain but eagerly; nor as being lords over those entrusted to you, but being examples to the flock; and when the Chief Shepherd appears, you will receive the crown of glory that does not fade away.
3. The apostle Paul set a godly example to teach others how a Christian ought to live.
1 Cor. 4:15–16. For though you might have ten thousand instructors in Christ, yet you do not have many fathers; for in Christ Jesus I have begotten you through the gospel. Therefore I urge you, imitate me.
1 Cor. 11:1. Imitate me, just as I also imitate Christ.
2 Thess. 3:7–8. For you yourselves know how you ought to follow us, for we were not disorderly among you; nor did we eat anyone’s bread free of charge, but worked with labor and toil night and day, that we might not be a burden to any of you.
4. Paul taught new Christians at Thessalonica by his godly example and so they soon became good examples for others.
1 Thess. 1:5–7. For our gospel did not come to you in word only, but also in power, and in the Holy Spirit and in much assurance, as you know what kind of men we were among you for your sake. And you became followers of us and of the Lord, having received the word in much affliction, with joy of the Holy Spirit, so that you became examples to all in Macedonia and Achaia who believe.
5. Jesus warns us never to set a bad example and cause others to sin.
Matt. 5:19. “Whoever therefore breaks one of the least of these commandments, and teaches men so, shall be called least in the kingdom of heaven; but whoever does and teaches them, he shall be called great in the kingdom of heaven.”
Matt. 18:6. “But whoever causes one of these little ones who believe in Me to sin, it would be better for him if a millstone were hung around his neck, and he were drowned in the depth of the sea.”
Luke 17:1–3. Then He said to the disciples, “It is impossible that no offenses should come, but woe to him through whom they do come! It would be better for him if a millstone were hung around his neck, and he were thrown into the sea, than that he should offend one of these little ones. Take heed to yourselves. If your brother sins against you, rebuke him; and if he repents, forgive him.”
6. Don’t ever put a stumbling block in another person’s way.
Rom. 14:13. Therefore let us not judge one another anymore, but rather resolve this, not to put a stumbling block or a cause to fall in our brother’s way.
7. One must be ready to give up that which is in itself indifferent rather than to cause another to sin.
Rom. 14:19–21. Therefore let us pursue the things which make for peace and the things by which one may edify another. Do not destroy the work of God for the sake of food. All things indeed are pure, but it is evil for the man who eats with offense. It is good neither to eat meat nor drink wine nor do anything by which your brother stumbles or is offended or is made weak.
1 Cor. 8:1–13. (Paul deals with the matter of eating food sacrificed to idols.)
1 Cor. 8:9–13. But beware lest somehow this liberty of yours become a stumbling block to those who are weak. For if anyone sees you who have knowledge eating in an idol’s temple, will not the conscience of him who is weak be emboldened to eat those things offered to idols? And because of your knowledge shall the weak brother perish, for whom Christ died? But when you thus sin against the brethren, and wound their weak conscience, you sin against Christ. Therefore, if food makes my brother stumble, I will never again eat meat, lest I make my brother stumble.
