Sin must be resisted
2Cor 6:11 O ye Corinthians, our mouth is open unto you, our heart is enlarged. 12 Ye are not straitened in us, but ye are straitened in your own bowels. 13 Now for a recompence in the same, (I speak as unto my children,) be ye also enlarged.
14 Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness? 15 And what concord hath Christ with Belial? or what part hath he that believeth with an infidel? 16 And what agreement hath the temple of God with idols? for ye are the temple of the living God; as God hath said, I will dwell in them, and walk in them; and I will be their God, and they shall be my people. 17 Wherefore come out from among them, and be ye separate, saith the Lord, and touch not the unclean thing; and I will receive you, 18 And will be a Father unto you, and ye shall be my sons and daughters, saith the Lord Almighty.
7:1 Having therefore these promises, dearly beloved, let us cleanse ourselves from all filthiness of the flesh and spirit, perfecting holiness in the fear of God.
Col 3:1 If ye then be risen with Christ, seek those things which are above, where Christ sitteth on the right hand of God. 2 Set your affection on things above, not on things on the earth. 3 For ye are dead, and your life is hid with Christ in God. 4 When Christ, who is our life, shall appear, then shall ye also appear with him in glory. 5 Mortify therefore your members which are upon the earth; fornication, uncleanness, inordinate affection, evil concupiscence, and covetousness, which is idolatry: 6 For which things' sake the wrath of God cometh on the children of disobedience: 7 In the which ye also walked some time, when ye lived in them.
1Jn 2:1 My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous: 2 And he is the propitiation for our sins: and not for ours only, but also for the sins of the whole world. 3 And hereby we do know that we know him, if we keep his commandments.

Gal 2:17 But if, while we seek to be justified by Christ, we ourselves also are found sinners, is therefore Christ the minister of sin? God forbid.
