Romans 6:1,2,11-14
1 What shall we say, then? Shall we go on sinning so that grace may increase? 2 By no means! We died to sin; how can we live in it any longer? 11In the same way, count yourselves dead to sin but alive to God in Christ Jesus. 12Therefore do not let sin reign in your mortal body so that you obey its evil desires. 13Do not offer the parts of your body to sin, as instruments of wickedness, but rather offer yourselves to God, as those who have been brought from death to life; and offer the parts of your body to him as instruments of righteousness. 14For sin shall not be your master, because you are not under law, but under grace.
Psalm 66:18
18 If I had cherished sin in my heart, the Lord would not have listened;
Psalm 51:10
10 Create in me a pure heart, O God, and renew a steadfast spirit within me.
1 Corinthians 6:9-20
9Do you not know that the wicked will not inherit the kingdom of God? Do not be deceived: Neither the sexually immoral nor idolaters nor adulterers nor male prostitutes nor homosexual offenders 10nor thieves nor the greedy nor drunkards nor slanderers nor swindlers will inherit the kingdom of God. 11And that is what some of you were. But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of our God. 12"Everything is permissible for me"-but not everything is beneficial. "Everything is permissible for me"-but I will not be mastered by anything. 13"Food for the stomach and the stomach for food"-but God will destroy them both. The body is not meant for sexual immorality, but for the Lord, and the Lord for the body. 14By his power God raised the Lord from the dead, and he will raise us also. 15Do you not know that your bodies are members of Christ himself? Shall I then take the members of Christ and unite them with a prostitute? Never! 16Do you not know that he who unites himself with a prostitute is one with her in body? For it is said, "The two will become one flesh." 17But he who unites himself with the Lord is one with him in spirit. 18Flee from sexual immorality. All other sins a man commits are outside his body, but he who sins sexually sins against his own body. 19Do you not know that your body is a temple of the Holy Spirit, who is in you, whom you have received from God? You are not your own; 20you were bought at a price. Therefore honor God with your body.
