We know that the law is spiritual; but I am unspiritual, sold as a slave to sin.
I do not understand what I do. For what I want to do, I do not do. But what I hate, I do.
So this is the principle I have discovered: When I want to do good, evil is right there with me. For in my inner being I delight in Gods law. But I see another law at work in my body, warring against the law of my mind and holding me captive to the law of sin that dwells within me.
Walk by the Spirit, and you will not gratify the desires of the flesh. Above all else, guard your heart, for everything you do flows from it.
Galatians 5:16, Proverbs 4:23.
It can be done.
