We never conquer sin by adding more rules. Sin is conquered by sanctification – the process of becoming holy, more like Christ – a lifelong process!
If you prepare your heart, and stretch out your hands toward Him;
If iniquity (sin) be in your hand, put it far away, and allow no evil (wickedness) to dwell in your tent, then you will lift up your face without shame; you will stand firm and without fear. – Job 11:13-15
You can do this! I can do this! We can do this! Yes we can, because God is on our side!
