(Pro 9:7 KJV) He that reproveth a scorner getteth to himself shame: and he that rebuketh a wicked man getteth himself a blot.
This is not telling us to refuse to “reprove” (correct NASB) (3256) or “rebuke” (reprove NASB) (3198). If you have read your Bible you know that it is expected when the timing is right. What is being declared is that it is a waste of time on some people.
You may have noticed that some people refuse to hear your simple English. It is a rare find if you can locate someone who will admit to being a Calvinist or a liberal. Or if you really want to find out what it feels like to ram your head against a block wall, find a “journalist” and try to convince them that they have a liberal bias. The same thing happens when you confront people on spiritual issues they don’t want to hear.
So? Keep your powder dry but don’t use a rifle to shoot at hornets. They may need it but you won’t touch them.
