Read Genesis 20
Focus on verse 9
This is one of the times when according to my cultural understanding of right and wrong, I do not understand how God justifies Abraham in this situation. Abimelech takes Sarah as a wife, with the understanding that she is Abraham’s sister – this would be an act of kindness and trust in the forming of an alliance with Abraham. In return, he finds out Abraham deceived him, and that now he (Abimelech) is being punished by God for taking another man’s wife.
Then Abimelech called Abraham and said to him, “What have you done to us? And how have I sinned against you, that you have brought on me and my kingdom a great sin? You have done to me things that ought not to be done.” (v. 9)
Somehow this just does not seem fair, not even with the lame explanation Abraham gives in regard to how “technically” she really is a half sister.
Perhaps this simply is another indication of how God is faithful to his promise to bless Abraham and give him possession of the land? It would seem God’s blessing upon Abraham is not contingent upon Abraham’s behavior and perhaps not even on his faith? In this case it seems God’s blessing is contingent entirely upon God’s own will and desire to bless Abraham.
I suspect this may also be true of our salvation…that our salvation is not contingent upon our obedient behavior or the strength of our faith. Rather, it is contingent only upon our willingness to accept the grace that God has shown us through the life, death and resurrection of Jesus Christ. Could it really be that simple?
