 He said, now, next year I'm going to give you a son. But wait a minute, I'm 100 years old, I'll be 100 years old, and my wife 90, 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 100 years of age, a wife 90, a son. Now, the question is, could he do it? Yes, he could. Did it take a miracle? Yes, it did.
