“Arise, walk in the land through its length and its width, for I give it to you.” Then Abram moved his tent, and went and dwelt by the terebinth trees of Mamre, which are in Hebron, and built an altar there to the Lord. (Genesis 13:17-18)a. Arise, walk in the land through its length and its width, for I give it to you: As a token of Abram’s reception of the land by faith, God wants Abram to explore the land of promise, to walk through it as if it were his, though he does not have “title deed” to it yet.
i. In the same way, God wants us to explore our “land of promise,” His Word, where God has given to us exceedingly great and precious promises (2 Peter 1:4), where He has given us all things that pertain to life and godliness (2 Peter 1:3). He wants us to walk through this “land,” possessing it by faith.
b. Dwelt by the terbinth trees of Mamre, which are in Hebron: The name Mamre means, “vision.”; Hebron means “communion.” Abram is once again walking in the Lord’s vision for him and in communion with the Lord.
Right or left, Abram knew he could trust God. He did it because he learned God would provide for his needs, and he did not have to worry about being too generous. Abram knew whatever Lot chose God would make sure Abram came out all right. Now, he is wiser and is willing to let God look out for his interests. Right or left, it didn’t matter to Abram, because God would be there. Because he trusted in God, Abram did not have to be obsessed with his own “rights” and neither do we. The only right we truly have is the right to go to hell. Everything else is the free gift of God and has nothing to do with our “rights.”
