This is the sort of stuff that gets cut out of my dissertation:
If God is determined to liberate and God then promises this liberation, the issue at hand is not simply one’s own experience of suffering at a given moment but also God’s very identity as able to surpass the historical contingencies and fulfill the promise. God puts his own identity, essentially, at risk in making the promise. In other words, with the promise it is not only about us, but also about God being faithful to himself and in his faithfulness to himself he is faithful to us. It is in this accomplishment of faithfulness that God, then, can be identified as God, as it is only God who is able to surpass all in order to accomplish all. God becomes knowable through the promises he makes and the promises he keeps. “I am” becomes “I am the God who brought you out of Egypt.” This then expresses God’s intent to be known through the horizon of history as the promises and the fulfillments identify, clarify, and substantiate his revelation of his self.
