In this chapter we see Abraham faltering in his faith in the same way he had done earlier in his life. The scenario was very similar to that related in Genesis 12, and Abraham falls into the same trap. We last saw Abraham overlooking the valley of the Dead Sea, interceding with God on behalf of the wicked cities of the plain. This is a place of high favour in Abraham’s life, when he seems to have grown to a position of wonderful friendship with God. Now, his faith falters and he sins.
It is interesting how the Bible is utterly realistic even about the heroes of the faith. There is no covering over Abraham's sin, but a realistic presentation of him in both his strength and his weakness, in both his faith and his fear, in his righteousness and in his sin. This is true for all our lives too.
While Abraham’s faltering faith comes as no surprise, the faithfulness of God to Abraham in his time of failure is amazing. In this passage especially, we see that it is God Himself who will bring about the fulfillment of the promises of the covenant, not really with Abraham's help, but despite it. And we see that the Lord is good to Abraham even when he deserves punishment.
There are things we can learn from these verses about our failure and God’s faithfulness. He gives us the opportunity to turn our lives back to him. He wants us to see his grace and faithfulness.
