There is such a thing as bondage in the Christian's life.
"Now if I do that I would not, it is no more I that do it, but sin that dwelleth in me."
This does not preclude the possibility to repent, but in the end, deliverance may come only by a Sovereign act of Grace.
" For we 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.
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."
As holy and righteous as any of us may deem himself, this enigma will manifest in the life of even the most devout Christian. In itself, it is but the confronting of the power of the satanic nature we all possess; and it will never, ever go away, even unto death.
The redeeming answer lies in Grace and Faith, and endurance; Deliverance comes, but mostly only on a daily basis, as we choose to die to us, and live to Him. This is the nature of baring our Cross; Embracing the Holy Spirit to slay us.
"This I say then, Walk in the Spirit, and ye shall not fulfil the lust of the flesh."
" For the flesh lusteth against the Spirit, and the Spirit against the flesh: and these are contrary the one to the other: so that ye cannot do the things that ye would."
Winning is learning how to die, to live. Often, it is not easy. It may be the hardest thing you ever do.
