Arm yourself with the thought that when Jesus died to free you from sin, you died to sin.
If God works to bring about obedience in our heart, then sin will not be lord over us, God will.
When we really see and believe what God is for us by grace through Jesus Christ, the power of wrong desires is broken.
Keep God first in your life by finding others who love God well and imitating them.
