I do full know well, but you keep making it a burden, we became perfect when we came to Christ and put on His righteousness, our Spirit cannot sin, end of Story, Christ is happy when men believe, is it not enough for you.
And what about your flesh if your Spirit cannot sin? Does it follow suit, or is it not one with your spirit? We are made in the image of God. And like Jesus who is the embodiment of the mind (Father) and Spirit (Holy Spirit), we are one. If you don't sin in your spirit, you won't in the flesh either. If you sin in the flesh, you have quenched your spirit from the control of the Spirit.
There was a doctrine of the Gnostics, and part of it was that our Spirit cannot sin, and that is all that counts. They believed that their flesh could sin, and in fact, should sin everyday so that grace could abound. It was a heinous, evil, unholy doctrine. Today, we have something similar, except for the sinning in the flesh on purpose so grace could abound. At least, I hope we are smarter than they were centuries ago. Are we?
