(Genesis 17:17,19) “Abraham fell face down and laughed as he said to himself, ‘Can a child be born to a man who is a hundred years old? Can Sarah give birth at ninety?’ . . . God replied: ‘Even so, your wife Sarah is to bear you a son, and you shall call him Isaac.'”
To some what we believe is possible with God is laughable. But as believers we look forward to joining with God in the last laugh.
