Proverbs 9:7 He that reproveth a scorner getteth to himself shame: and he that rebuketh a wicked man getteth himself a blot.
8 Reprove not a scorner, lest he hate thee: rebuke a wise man, and he will love thee.
9 Give instruction to a wise man, and he will be yet wiser: teach a just man, and he will increase in learning.
Here we are seeing that when we witness to sinner and they argue with us it does no good. If they argue with you it is better to just leave them alone. A lot times when we try to correct someone they get mad and it could cause them to hate us. We have often heard it said if a preacher does not step on his congregations toes pretty often he is not a good preacher. With this we can see if a wise man is corrected he is glad so he will have the chance to repent. Those who are wise are eager to take instruction from someone who knows a little more about the subject. The only people who can increase in learning are the ones who want to learn. Christians should always be ready to learn more no matter how well educated they are, God is always ready to give us more wisdom so we can grow in righteousness and be a better witness to those who are lost.
