Despite the failure and sin of Abram in the previous chapter, the Lord reaffirms his commitment to give him a land and a people—and he seals that covenantal commitment with the sign of circumcision. He makes it clear to us that his grace and forbearance do not remove the requirement of obedience, but actually reinforce it.

Abram and Sarai knew the promise of God, but grew impatient with God’s timeline, not seeing how the promise could be fulfilled. They took matters into their own hands to further God’s agenda—and the results were disastrous. In this messy incident, we see the cost of sinful self-reliance and the abundant grace of God.

When Abraham could not see the way forward for the fulfilment of the plans and purposes of God, the Lord reaffirmed the covenant and taught Abraham that he—the Lord—was his shield of protection and the substance and source of his reward. The promise-making and promise-keeping God is faithful and all-sufficient for his people.

The covenant blessing of God does not spare God’s people the experience of battling enemy forces, but it does guarantee their ultimate victory. Added to this, in a remarkable event (the encounter with Melchizedek) God adds renewed blessing, while pointing forward to the One who will fulfil the covenant promises in a day to come.

As Abraham begins to enter into the blessings of God in terms of land and goods and people, we see a godly spirit of generosity come through (and perhaps we see the start of a contrast with Lot). The blessing of God is meant to make his people a blessing to others.
