Did you know that Paul, the apostle of Christ also had similar struggles?
He wrote: For we all know that the law is spiritual: but I am carnal, sold under sin. For that which I do I allow not: for what I would, that do I not, but what I hate, that do I. If then I do that which I would not, I consent unto the law that it is good. Now then it is no more I that do it, but sin that dwelleth in me.
For I know that in me (that is in my flesh) dwelleth no good thing: for to will is present with me: but how to perform that which is good I find not. For the good that I would, I do not: but the evil which I would not, that I do. Now if I do that I would not, it is no more I that do it, but sin that dwelleth in me.
I find then a law, that, when I would do good, evil is present with me, for I delight in the law of God after the inward man: but I see another law in my members, warring against the law of my mind, and bringing me into captivity to the law of sin which is in my members. O wretched man that I am! Who shall deliver me from the body of this death? I thank God through Jesus Christ our Lord. So then with the mind I myself serve the law of God, but with the flesh the law of sin.
(Romans 7:14-25)
