What is heretical is believing Jesus was powerless to make us sinless now. You believe until we have new bodies, we still sin willfully. What has the body to do with the mind.
"What does the body have to do with the mind?" Why would you even ask that? Obviously, the body has *everything* to do with the mind! The brain is part of the body! The mind functions as a bodily function, and actually directs the body!
Yes, we still sin *willfully* when we are Christians. Every time you get excessively angry, or distort the truth out of biased interests, you are showing "willful sin" at work in your mind and body. You do things that are not in perfect accord with the Spirit of Christ.
I'm here to say that Christ understands that, and he still loves you. That is his grace. He brings us along, trying to temper us, trying to moderate what we do and say, to hopefully mitigate the damage we do to ourselves and others. This is God's grace, sister. And this is the life of a Christian--one of correction, of living by grace, of growing up, getting strong, and fighting to be aligned with Christ.
Knowing we are sinning while doing so, because we can't help it. If we didn't have the Spirit, that would be true. Our lusts would still control us.
Living by grace, and being imperfect is not the same thing as living regularly in our carnality and sin. You are conflating two very different things: living carnal lives and living flawed but spiritual lives generally. We are given a new nature so that we live spiritual lives, even while knowing we won't be perfect. We will fail at times, and actually everything we do will be slightly tainted by self interests.
But the idea is that we live *overcoming lives,* regularly choosing to live in relationship with God, in fellowship with Christians by the one Spirit. Our flawed personalities do not prevent us from living spiritual lives generally, from ministering by the Spirit.
The Word of God says of those who sin willfully as you believe: 29 Of how much worse punishment, do you suppose, will he be thought worthy who has trampled the Son of God underfoot, counted the blood of the covenant by which he was sanctified a common thing, and insulted the Spirit of grace?
That isn't what that passage is talking about. That's talking about apostasy from Christianity--not flaws in our spiritual walk! You do a terrible disservice in your theology, attributing apostasy to imperfect Christians, to Christians who sometimes err.
Do you notice we've already been sanctified (past tense).
Sanctification is the process by which God sets us aside from the carnal world to be instruments of his righteousness, through the covenant of Christ. Being hand selected by God for Salvation and for ministry does not require perfection.
We have Christ's atonement, not just to save us initially, but more, to continually cleanse us of our imperfections. That enables us to minister, and not be disqualified. We can, however, be disqualified, if we wander too far in the direction of apostasy.
