 He said, now, next year I'm going to give you a son. But wait a minute, I'm a hundred years old, I'll be a hundred years old, and my wife ninety, and you're going to give us a son? Isn't this a little late? God said, trust Me. Now, that's what God promised. He promised to give a man a hundred years of age, your wife ninety, a son. Now, the question is, could He do it? Yes, He could. Did it take a miracle? Yes, it did.
