Genesis 13 tells us that when Abram left Egypt, he came back to the place between Bethel and Ai, where he had built an altar, before he had moved to Egypt. There he called on the name of the Lord, meaning that he worshipped God again. Then at the end of the chapter, we learn that Abram moved from there to the plain of Mamre (the Amorite friend of his), on Hebron, where again he built there an altar to worship the Lord. From this we see that wherever Abram went he built an altar to worship the Lord. In fact, it is the first thing that is recorded of Abram’s doings, in any new place.

Points to ponder:
Worship was an integral part of Abram’s life. He remembered the Lord first in whatever place he was … as a priority. Each one of us are in different places in our lives, but what is important is that our life is surrounded by worship bookends … in the beginning and in the end, wherever we are. Let our life be built as an altar and our body be presented on it, as a living sacrifice which is the reasonable action of worship (calling on the name of the Lord) (Romans 12:1). Is worship an integral part of our life, wherever we go? Think about it!

Genesis 13:3-4,18 (KJV)
3 And he went on his journeys from the south even to Bethel, unto the place where his tent had been at the beginning, between Bethel and Hai;
4 Unto the place of the altar, which he had make there at the first: and there Abram called on the name of the Lord.
…
18 Then Abram removed his tent, and came and dwelt in the plain of Mamre, which is in Hebron, and built there an altar unto the Lord.
