You're sounding dangerously like a calvin type person.I'm quite convinced that God doesn't judge our actions if we've believed Him (in a condemning way), but that if He's received us as adopted children through faith in His Son, He disciplines us as His own and loves us through our lives and beyond them to eternal life. This is the teaching of scripture. Of course, the scripture warns us that if we are not disciplined by God, then we are not legitimate children.
I believe we are children of God for as long as we want to be.
He doesn't force us.
Discipline?
Yes. It seems to come naturally when we don't adhere to God's rules.
I THINK I agree with you. (except for the calvin part)
