We know that our old self was crucified with him in order that the body of sin might be brought to nothing, so that we would no longer be enslaved to sin. Romans 6:6 esv
In Christ we already have victory over sin! When we least expect it a spiritual attack comes. Life has a way of draining us sometimes to a point where our spirits just feel empty. At that point we are highly susceptible to temptation. At times we feel as if the sinful habits that cling to our souls will always have a hold on us. But in Christ Jesus we have already been made free from sin.
Your victory over sin has already been attained in Christ. Now it is up to you to walk into it and realize who you are in Him. Whatever you feel has you bound right now has already been defeated over 2000 years ago, if you have been born again. In accepting the Lord Jesus you have become new. Enjoy your fresh start. Live the way God meant you to; holy, productive, free!
