Earlier in Genesis, God had promised Abraham and Sarah a child. ” I will make you into a great nation.” (Genesis 12:2) But like most of us…they allowed fear and doubt to overshadow their hope and expectations. For in this verse, God led Abraham out into the cloudless night sky to observe the stars, (they estimate there are 1 Billion Trillion stars in our universe), and then reassured him that his offspring would be as numerous. God does this for us also. He can cause a Bible verse to suddenly become alive and take on new meaning…banishing doubt and bolstering our faith in Him. He can strip away fear and strengthen our trust by bringing into remembrance all the things He’s done for us in the past. And just like Abraham, we too can look up into that starry sky and see God’s wonder, power, and majesty…and be assured of His love and faithfulness for us.
So here we have this very old couple…the husband is 99 and his wife is 90. At that age, it’s virtually impossible physically for that couple to conceive a child together. Yet here in this Scripture the Lord is promising them children…and all He asks of them is to trust and obey. Many think at a certain age they can “retire” from doing God’s work…but God’s saying, “No way!” There is no retirement age in God’s Kingdom…and there’s no impossibility that God can’t overcome…and all He asks of us, is to trust and obey.
