A true believer is no fool… so help him grow in wisdom through loving confrontation.
Proverbs 9:7-9
Whoever corrects a mocker invites insults;
whoever rebukes the wicked incurs abuse.
Do not rebuke mockers or they will hate you;
rebuke the wise and they will love you.
Instruct the wise and they will be wiser still;
teach the righteous and they will add to their learning.
