A book that only claimed to be from God would not record the failings of a great man like Abraham. since the Bible is from God, it tells us of a second time Abraham failed to trust in God's care (20:1-18). Ironically, God got him out of the trouble in which he placed himself. Despite Abraham's lack of trust, the next chapter tells us God kept his word. Sarah had a child exactly when God said she would. In fact, the child was born at the very time God had set (21:1-2).
