Abraham's live was exemplified in his faith in God. It was first seen as he left his secure home in Ur, and then deepened as he was forced to wait for God to fulfill His promise even while he was very old in age. It was epitomized as he was willing to trust God and sacrifice his son, Isaac. In each instance, God allowed Abraham to wait on Him, in order to cultivate a deeper trust and dependence on God to fulfill what He promised. The same pattern can be helpful for Christians today as they try and deepen their faith.
