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.
