Oh my gosh! Have you even read anything I've said?????
There are things in the law I do not HAVE to do, because Christ has already done for me what those things in the law sought to accomplish.
God fulfilled all of the law for me in regard to being made legally righteous in his sight, cleansed from all guilt of sin. But in regard to actually keeping the law 'in action and in truth' (1 John 3:18) I do that, through the power of the Holy Spirit. And it's something I will always do to the very end of my life. God will never do that for me. That is my responsibility and obligation. I am to walk according to, and in step with the Spirit. I wish God did that for us. How different this forum would look if God did that for us.
I don't suppose it. It's what the Bible says.
I didn't decide which laws don't have to be literally kept and which ones do not. The Bible explains this for us. And the Bible says you are justified (shown to be righteous, not made to be righteous) when you keep God's commmands—the ones that remain to be kept by us.
That is where the blood of Christ comes in. Because I trust in the blood of Christ, if I fail to keep the law because of ignorance or weakness, that failure is forgiven by my High Priest, Jesus, through his blood that he has already sacrificed for me. But if I willfully and defiantly don't keep the laws that remain to be kept by God's people, I am NOT forgiven. Jesus the High Priest does not have that sin covered (I have to come to the Lord to have it covered.....while I am allowed to come to him).
If I die in that state of defiant, willful unbelief and rejection of God's grace I will go to the fiery place, not into the kingdom of God. Does that mean I lost my salvation, or never had it to begin with? What does it matter? I'm going to the fiery place. That's what matters. And that's what the church doesn't talk about, preferring instead to argue about whether once saved always saved is true or not. An argument, one way or the other, that does not change the fact that if you die in willful sin in a rejection of the blood of Christ you are going to the lake of fire, not into the kingdom of God. That's the part that is not in dispute. But we don't talk about that. We talk about the meaninglessness, right or wrong, of once saved always saved instead.
