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 equally stupid both times. In Genesis 12:11, 13 Abraham told Sarah, “I know what a beautiful woman you are…. say you are my sister.” If they were merely brother and sister, then this beautiful woman would be 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. This was unloving to her and unbelievable in that Abraham and his men had just defeated a cohort of kings in Genesis 14. If Abraham and his men were powerful enough to liberate Lot and Sodom from these kings, surely they could have protected Abraham’s life and Sarah from being abducted.
This incident shows what happens when we live in fear instead of faith in God’s promises. We make foolish decisions. God protected Abraham because of his covenant promises to Abraham that he would become a great nation through the son born to Sarah. But God would have been just to allow the consequences of Abraham’s foolish actions to happen.
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.
