I find the concept that Abraham answered the call and Noah answered the call of God a bit weird. We are use to all being called to repentance, but in the Old Testament frew actually heeded that call.
Abraham did, his son Isaac did and his grandson Jacob did. Yet they each had to decide for themselves. Just as we do today.
Jacob had material possessions, love, children land, all he could want and still he was seeking a blessing.
When Jacob finally accepted God as his God then he was fulfilled.
