And sense the human condition is constant failure, God comes along and picks us up without any effort being made on our part. One caveat is we have to be His children.
Phl 1:6 Being confident of this very thing, that he which hath begun a good work in you will perform it until the day of Jesus Christ:
God can only present His promises to us. He will not supersede our own choices. I agree that God is always there for us, but there are times in life when that simply isn’t enough for everyone.
Again, this isn’t God’s failing. It’s ours. Do keep in mind, we are not perfect. We can try to live good lives, and love God, and respect Him, but there can be times when the human condition is too weak to prevail.
None the less, I do see that failing in this context to be the unpardonable sin.
