What bargain did Abraham make? I am no longer part of that specific Abrahamic covenant. Nobody is. In Christ, 'there is no longer Jew or Greek'. In God's eyes, we are all the same.

Abraham had faith in Jesus. I don't have a problem with people associating themselves with Abraham if they want to, but they should at least be honest and admit that they don't share his faith in Jesus.

Apart from Jesus, 'Abrahamic faith' means nothing. Faith in what? Himself?
