A survey of Abraham's life, both his highs and lows, teaches us that even though he would be the key to God's solution to the problem of sin, he is far from being a perfect man. And that should also be encouraging for us because God is not looking for perfect men and women to accomplish his purposes. He is looking for people with their weaknesses who are still willing to exercise faith in him and strive to please him by obeying him with the strength he gives them.
