In a time when people believed in so many gods, Abram and Melchizedek proclaim the existence of only One God, the one who created heaven and earth, and who has all the power over any situation, like that of the war they had just lived. Today, there still are many modern gods, such as money, fame, social status, a lover, etc., but there is only one God, the true God, the Most High God, also referred to as The Lord in the passage.
