A person descended from Abraham can look back in history for comfort to a promise by God. The promise was to descendants of Abraham so it seems to many of his descendants that this is enough. The news is that it is not enough but spiritual descent from Abraham is needed which is what Jesus came to bring - both to blood descendants and, wondrously, to blood non-descendants. I don't know which I am but I know it won't matter as long as He makes me a spiritual descendant as I follow Him and the Holy Spirit sent by God in Jesus' name.
