Romans 4: 19-20: “Without becoming weak in faith he contemplated his own body, now as good as dead since he was about a hundred years old, and the deadness of Sarah’s womb; yet, with respect to the promise of God, he did not waver in unbelief, but grew strong in faith, giving glory to God.” How did Abraham and Sarah conceive? The same way Mary did: through faith. Mary believed against all odds (no man) and took immediate action; she visited Elizabeth. Abraham and Sarah believed against all odds (dead reproductive organs) and took immediate action; they visited each other. Belief always leads to action. In other words, if you pray for rain, you should carry an umbrella.
