I think most of us, when first reading this passage, can be excused for cocking our heads to the side and wondering out loud, “Could you be any more esoteric, Paul?” What exactly is he driving at with this comment about someone’s last will and testament? People change their wills all the time, don’t they? At least before they die, so why bring this up here? It seems, that Paul wants to again make the point that God had made a promise to Abraham, that all nations would be blessed through Abraham. And so, this discussion about a will is really about the ultimate provider of salvation – the law, or faith.
