Ephesians 4:22-24 (NIV)
22You were taught, with regard to your former way of life, to put off your old self, which is being corrupted by its deceitful desires;
23to be made new in the attitude of your minds;
24and to put on the new self, created to be like God in true righteousness and holiness.
1 Corinthians 6:18-20 (NIV)
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.
James 4:7 (NIV)
7Submit yourselves, then, to God. Resist the devil, and he will flee from you.
