There are times when God's people are faithful and full of trust in the Lord. But there are also many times when they are not. We are fickle people, swinging back and forth resting in the promises of God. And we can see Abraham doing the same thing during his life. But even through Abraham's fear and distrust while he is in the land of Egypt, God's plan prevails, because our faithlessness does not negate God's faithfulness. And it's when we trust in the promises of God, walking in faith, that we see God's good plan working through our lives.
"The Lord said to Abram, after Lot had separated from him, 'Lift up your eyes and look from the place where you are, northward and southward and eastward and westward, for all the land that you see I will give to you and to your offspring forever.'" Genesis 13:14-15
