Those who continue sinning, rebuke in the presence of all, that the rest also may fear. 1 Timothy 5:20

Nevertheless, God's solid foundation stands firm, sealed with the inscription; "The Lord knows who are his,  and everyone who confesses the name of the Lord must turn away from wickedness." 2 Timothy 2:19

We know that we have come to know him if we keep his commands,  Whoever says, " l know him, but does not do what he commands is a liar, and the truth is not in that person. But if anyone obeys his word, the love for God, is truly made complete in God. This is how we know we are in him: Whoever claims to live in him must live as Jesus did. 1 John 2:3-6

If we deliberately keep on sinning after we have received the knowledge of the truth, no sacrifice for sins is left , but only a fearful expectation of judgement and of raging fire that will consume the enemies of God. Hebrews 10:26-27

No one who continues to sin has either seen him or known him. No one who is born of God, will continue to sin, because God's seed remains in them,  they cannot go on sinning, because they have been born of God. 1 John 3:6,9
