Genesis 17: 1 When Abram was ninety-nine years old the Lord appeared to Abram and said to him, “I am God Almighty; walk before me, and be blameless, 2 that I may make my covenant between me and you, and may multiply you greatly.” 3 Then Abram fell on his face. And God said to him, 4 “Behold, my covenant is with you, and you shall be the father of a multitude of nations.
Like with Noah, God had earlier told Abram to "Go", and he did. Now that Abram had been going for a while, God says "I have plans for you and your descendants." It is often after we have been walking and talking with God for a while, learning to listen to His leading, that He begins to show and tell us what His plans are, so we know where we are heading and why we are going there. Our relationship with God is for the long haul - not just to bail us out when things are bad, or we have really messed up. Let us learn to listen as He directs, then the bigger picture will eventually become a little clearer.
