Read Genesis 20, Nehemiah 9 and Proverbs 2. This devotional is about Genesis 20.
Abraham and Sarah did this, “We’re brother and sister” thing before back in Genesis 12:10-20. On that occasion, they were in Egypt; here they are in Gerar. In Genesis 12, God protected Sarah just as he did here.
But this was stupid both times, even more so the second time after the close call back in Genesis 12. In Genesis 12:11, 13 Abraham told Sarah, “I know what a beautiful woman you are…. say you are my sister.”
But think about how that would sound to man. “Hi, I’m Abraham and this beautiful women here is my sister Sarah.”
Well, if they were merely brother and sister and there’s no husband introduced, then it would be reasonable for a man to conclude that this beautiful woman was single and available for anyone who wanted her.
Predictably, that’s what happened; she was added to the harem of Pharaoh (Gen 12) and Abimelek (here in Gen 20). In both cases, Abraham lost his wife and put God’s promises in jeopardy. In both cases, only God’s miraculous intervention preserved Sarah and allowed her to become the covenant mother that God had promised she would be.
So why would Abraham do this–knowingly and predictably put his wife in a situation where she would be taken by other men?
The answer–in both cases–was fear. Abraham was afraid of being killed so that someone could get to Sarah (v. 11).
So he just lied and made Sarah available.
That was unloving to her and unnecessary. Abraham and his men had just defeated a cohort of kings in Genesis 14. If Abraham and his servants were powerful enough to liberate Lot and Sodom from these kings, surely they could have protected Abraham’s life and Sarah from being abducted.
And, how often does it actually happen where a man kills another man to be with his wife? I know there are news stories where that kind of thing happens but I’ve never personally met anyone in that situation. If a man did that–killed another man to take his wife–the other men who lived around the killer would gang up on him and kill him.
So, Abraham’s fear was unspiritual, irrational, and far adrift from reality.
This incident shows what happens when we live in fear instead of faith in God’s promises; namely, we make foolish decisions. God protected Abraham because of his covenant promises that Abraham would become a great nation through the son born to Sarah. But God would have been just to allow Abraham to live through the consequences of the foolish, fear-filled decisions he made.
Are you living your life in fear instead of in faith? Do you use lies and deception to manipulate others instead of trusting God to care for you and provide for you? It is easy and tempting for us to fall into a similar trap as Abraham. Learn from his negative example in this instance and trust God instead of acting in fear.
