A kind heart does not rebuke much, and even if he rebukes, it will not be with hurting words.
See how the Lord treated His disciple Peter who denied Him thrice, cursing and swearing, saying, “I do not know the Man.” (Mt 26: 69-74)! When the Lord met him after the resurrection, He did not remind him that he denied Him thrice with oaths and cursing, but to blame him, the Lord only said to him thrice, “Simon, son of Jonah, do you love Me more than these?”
