In this passage we see how Abram repents after he experiences the faithfulness of God even in the fact of Abram's faithlessness. Abram is trusting the promises of God again, so much so that when faced with another big decision - where will he live vs. where will his Nephew live - he trusts God and let's Lot have first dibs. Not only that, but when faced with another crisis of safety, Abram trusts God, leans into God's power, and is used to route an army that far outnumbered his house militia. Finally, after all that, rather than falling into pride, when faced with another decision to trust himself and other men, Abram decided to sear his allegiance to the Lord through a mysterious figure called Melchizedek - King of Peace, King of Righteousness. HINT: Melchi is pointing us to someone else!
