13-15 That famous promise God gave Abraham—that he and his children would possess the earth—was not given because of something Abraham did or would do. It was based on God’s decision to put everything together for him, which Abraham then entered when he believed. If those who get what God gives them only get it by doing everything they are told to do and filling out all the right forms properly signed, that eliminates personal trust completely and turns the promise into an ironclad contract! That’s not a holy promise; that’s a business deal. A contract drawn up by a hard-nosed lawyer and with plenty of fine print only makes sure that you will never be able to collect. But if there is no contract in the first place, simply a promise—and God’s promise at that—you can’t break it.
16 This is why the fulfillment of God’s promise depends entirely on trusting God and his way, and then simply embracing him and what he does. God’s promise arrives as pure gift. That’s the only way everyone can be sure to get in on it, those who keep the religious traditions and those who have never heard of them. For Abraham is father of us all. He is not our racial father—that’s reading the story backward. He is our faith father.
