Not unless you were being purposely obtuse.
There was no such thing as a Christian until Jesus was raised from the dead.
So? Abraham believed in the promise of the Messiah. You know, the One promised in the Garden of Eden to Adam and Eve.
Abrahams faith is what mattered, but not from a Christian perspective.
Right, because the God he worshiped was some other God? Are not Christians sons of Abraham? Heirs according to the PROMISE? In case you want to continue this line, read Galatians 3. We are just like Abraham, we live by faith, we haven't seen Christ either. Yet it too is very personal and experiential.
You and I have different perspectives on Christianity, apparently. That’s ok. It’s an iron sharpening iron sort of thing.
