Should one's lack of faith make the Faith of God of no affect? God forbid! Let God be true and very man a liar.
I only know the word says that Jesus said, we who commit sin are a slave to it and if the Son should set us free, free we are indeed.
This freedom Paul also alludes to as being accomplished. In Romans 8 He says that Jesus has set us free from the Law of Sin and death that the righteousness of the Law be fulfilled in us who walk after the Spirit and not after the flesh. This Law of sin is disclosed in chapter 7. There Paul through the Spirit states, For the good that I would I do not: but the evil which I would not, that I do. And saying this He states that it is no longer him , but the sin that dwelleth in Him. He then says this is a law and says that this law is that when he would do good evil is present with Him. He delighted after the Law of God in His inner most being, but this other law, that while he wanted to do good he couldn't, and the evil he did not want to do, that he did was warring against the Law of His mind, the Law of God and it was bringing him into captivity, to this law of sin which was in his members. Thank God the Lord has set us free from this Law of sin and death that the righteousness of the Law be fulfulled in us who walk after the Spirit and not after the flesh. For if we walk after the Spirit we will die. But if we through the Spirit do mortify the deeds of the Body we shall live. For as many as are led by the Spirit of God, they are the sons of God. For ye have not received the spirit of bondage again to fear; but ye have received the Spirit of adoption, whereby we cry, Abba, Father.
Rom 7:19 For the good that I would I do not: but the evil which I would not, that I do.
Rom 7:20 Now if I do that I would not, it is no more I that do it, but sin that dwelleth in me.
Rom 7:21 I find then a law, that, when I would do good, evil is present with me.
Rom 7:22 For I delight in the law of God after the inward man:
Rom 7:23 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.
Rom 7:24 O wretched man that I am! who shall deliver me from the body of this death?
