The point, which seems to have passed you by,
Did Abraham know of Christ?
Your answer? _
Was Abraham saved?
Apparently so.
As for circumcision, Paul just spent chapters on discussing that circumcision is nothing and uncircumcision is nothing.
No, the point is that you are flat-out contradicting the Word of God, and do not understand how a man is justified in the sight of God.
You said “I believe Abraham was saved in leaving his home and moving to Israel, in trusting the promises of God, and submitting to them by actually acting and following through.”
This is salvation by doing something (works).
The Word of God says that “We say that faith was counted to Abraham as righteousness.” - BEFORE he did anything (circumcision, moving, offering Isaac, etc....)
This is a critical distinction. Abraham was counted righteous by believing God. Nothing more. The fact that he followed through and obeyed was evidence of his belief, not the basis on which he was counted righteous.
BK - “Did Abraham know of Christ?”
The Bible doesn’t tell us how much Abraham knew, but he certainly believed that God was going to provide a way of salvation for mankind.
BK - “Was Abraham saved?”
Yes.
BK - “As for circumcision, Paul just spent chapters on discussing that circumcision is nothing and uncircumcision is nothing.”
I understand that. That was provided to prove that Abraham was counted righteous because of his faith before he DID anything. Which proves you wrong.
