While the Bible is definitely awesome, sometimes it can be a challenge to read. Often we need to back out of the details a bit, remember this is the story of God and then look for the storyline. We then can go back into the details and see what themes exist. Genesis 13-14 are exactly this. What seems to be just weird stories actually turn out to be a unified story that shows how Abram refused to compromise in the face of temptation.
