HOW TO OVERCOME SIN
Identify the sin. Confess it. Don't excuse it. 1 Cor. 10:13 says that God always provides a pathway for escape. Admit to God that you didn't take his way out.
Repent. In your words and actions tell God that you will not go back to that sin again. Then prepare to overcome by removing tempting obstacles.
Keep in step. Gal. 5:16 says, "So I say, live by the Spirit, and you will not gratify the desires of the sinful nature." (NIV) Fill yourself with the Words of God. Listen for the Spirit's gentle, protecting direction in your life. Respond to his conviction in the moment. Fill your life with worship and thanksgiving. When your spirit, soul and body are filled with worship and the Word of God, temptation does not have room to grow.
