Grace and promise

 Romans 9: 10-13  To Rebecca, also, a promise was made that took priority over genetics. When she became pregnant by our one-of-a-kind ancestor, Isaac, and her babies were still innocent in the womb—incapable of good or bad—she received a special assurance from God. What God did in this case made it perfectly plain that his purpose is not a hit-or-miss thing dependent on what we do or don't do, but a sure thing determined by his decision, flowing steadily from his initiative. 

What a beautiful description of grace and promise.
