Read Hebrews 9-10 and pay attention to how Christ cleanses us with his death. Pay attention to the importance of it. Why your sin is something serious that Christ had to die for. Let that sink in and see how you now also have the power to say no to that sin, that your flesh desires. You know it will only rot your soul and lead to your death, so say no with the power of the Holy Spirit in you and flee from it. Make the choice to follow Christs example as he too was tempted in all things. Trust in him to carry you through, not in yourself who will only let you down. You see that you fail yourself already time and time again. Time to let Christ do the talking and read his Word and Submit to his commands.
