Abraham never ceased to be the path, or rather, the example of the path to salvation.
Gal 3:29 And if you belong to Christ, then you are Abraham's descendants, heirs according to promise.
Abraham was saved by faith, so are we. This is the entire theme of the Bible.
We are Abraham's by adoption.
I do not have to follow Abraham for salvation. In fact, it would be wrong for me to seek salvation by following Abraham and the subsequent ways.
Abraham was...Christ is!
