This is the story of ultimate faith, though to be fair I imagine the opportunity for advancement was limited for Semitic septuagenarians in the land of the Chaldeans. Still it took a leap of faith for Abram to go home and tell Sari to pack the bags and load the camel because God told him he was destined for favored nation status in a “God only knows where” land. So while it is the promised pot of gold at the end of the rainbow that makes the offer tempting it is ultimately Abraham’s trust that God can deliver that gets him to leave the center of civilization to wander the wilderness. Whether he knew it or not God blessed Abraham to be a blessing, even with the caveat about the cursed, since “all peoples will be blessed” would not be “all” without them. When you read the rest of the Abraham story his trust was less than trust-worthy and he did as much maneuvering as following. Of course we do the same and before leaving country, people and home we generally “trust but verify”. In the very end Abraham put his trust where his heart was when with the seed of the promise on the altar of sacrifice and his hand raised to do the unthinkable God intervened and spared the only son. For us it is not a ram but the God of promises who is caught in the thicket on Calvary’s hill and the only Son not spared is cursed so that we might be blessed to be a blessing.
