Abraham is the most significant figure in the Bible with the only exception being Jesus Himself. It might come as a shock to learn that God’s choice of Abraham has nothing to do with Abraham’s worthiness. One commentator 
added, “God does not look down from heaven to find a person who has a bit of saving faith or a bit of righteousness and then say, ‘Oh, isn’t this wonderful! I’ve found somebody with a little bit of true faith! That makes it possible for me to save him. I think I will.’” No, not at all. According to Genesis 6:5 when God looks down from heaven upon the sons of man he sees only evil in our hearts. Romans 3:10-12 says, “There is no one righteous, not even one; there is no one who understands, no one who seeks God. All have turned away; they have together become worthless; there is no one who does good, not even one.”
Abraham is no exception! We know that his father worshiped the moon god of Ur and trafficked in idols. That trait was handed down to his great grandchildren. Jacob still maintained household idols. He was told to leave his family and their household. He took many of them with him! Abram was called from Ur to go to the Promised Land but only went half way to Haran and stayed there for 20 years. These chapters are not about Abraham’s faithfulness to God, but it’s about God’s faithfulness to him. God’s promises to Abraham had to do with the promise of Genesis 3:15. The seed of the woman that would crush Satan’s head would come through him and his wife Sarah. He lied about his wife to Pharaoh and Abimelech to protect himself – putting the promised seed of the woman in jeopardy. God had to miraculously intervene in both cases. He doubted God and called Eleazar his heir! He doubted God and called Lot his heir! He doubted God and took Hagar to produce Ishmael as his heir.
Yes, Abraham, the great patriarch of faith, had his own hang ups and was anything but perfect. But God was faithful. Abraham was on a faith journey, and like Abraham our future rests upon God’s faithfulness not our own. All along the way we are learning that we can trust God and even if it takes a miracle, He’ll ensure our safe arrival. One commentator said, “God is always dependable, while we may not be at times. When we face setbacks, God is faithful. When we face guilt, God is faithful. When the bank account goes, God is faithful. When a loved one dies, God is faithful. When we know we have been faithless, God is faithful.” God is the only real marine; Always faithful!
