From there Abraham journeyed toward the region of the Negeb, and settled between Kadesh and Shur. While residing in Gerar as an alien, Abraham said of his wife Sarah, “She is my sister.” And King Abimelech of Gerar sent and took Sarah. Genesis 20:1-2
This is the second time that Abraham has passed off Sarah as just his sister and not also his wife. Both times, kings took Sarah into their households, presumably as a wife. Sarah was quite old at the time of these events, so she would have been seen as useless in the ability to bear children. So why would these kings want to take an older, alien woman as a wife? Perhaps it was a show of power; they could take a woman from a stranger in their land with no fear of retribution.
Abraham is known as the father of three great faith traditions. He is seen as loyal and obedient to God, even to the point of willingness to sacrifice his own son. Yet he, like every other human being, has feet of clay. He lies, he is a coward, he is selfish and he is self-centered. And God loved him nonetheless. In that story we can find hope for every one of us.

Here is the story of the first time Abraham lied about his relationship with Sarah (Genesis 12:10-20).
God, I let you down every day. Every day I am re-energized by your grace. Amen.
