Some people falsely teach that because God kindly does for us what we do not deserve, it ◄does not matter/is all right► if we continue to sin. Those people show by the way that they conduct their lives that they do not want to admit/accept that Jesus Christ is our only Master and Lord. It was written long ago {Someone long ago wrote} that God would condemn ◄such ungodly people/people like that whose lives are displeasing to him►. But some of those people have entered [MET] like crawling snakes into your congregations and oppose the truth about Christ, so you must resist/oppose them.
