Through faith also Sara herself received strength to conceive seed, and was delivered of a child when she was past age, because she judged him faithful who had promised. – Hebrews 11:11
Sara’s faith is joined with Abraham’s faith and they conceive a child in their old age. Neither had the power within them to make this happen. It was only by the omnipotence of God that such a miracle could take place. We even have record of Sara doubting the promise with laughter initially! Yet, God blessed them both to see His work in them and Abraham became the father of many nations.
We should closely examine this event in Sara’s life. When we think that the giant in front of us too huge to defeat, we should say with the LORD “Is anything too hard for the LORD?” Let us not doubt but have courage that the Lord will deliver on His promises.
