The covenant between God and Abraham is a foundational theme in the Bible, representing faith, promise, and divine purpose.

1. The Initial Covenant and Context

• Abraham, originally Abram, had been called by God to leave his homeland (Genesis 12:1–3).

• God promised him:

  1. Land (Canaan)

  2. Numerous descendants

  3. Blessing for him and all nations through him

• Abraham obeyed God by leaving Haran, demonstrating faith in action.

• However, Abraham was childless, and the fulfillment of God’s promise seemed uncertain, creating a need for reaffirmation of God’s covenant.

2.1. Abraham’s Concern and God’s Assurance

• Abraham expressed concern that he had no biological heir:

  “O Lord God, what will you give me, since I remain childless?” (Genesis 15:2)

• God responded by reassuring Abraham that he would have an heir from his own body and that his descendants would be numerous.

Spiritual Lesson: God’s covenant is not dependent on human ability but on His promise and faithfulness.

2.2. The Covenant Ceremony

• God instructed Abraham to prepare a covenant ritual: cutting animals in half and laying them opposite each other (Genesis 15:9–10).

• A deep sleep fell on Abraham, and God revealed future events concerning his descendants and their trials in a symbolic, prophetic vision (Genesis 15:12–16).

• A smoking firepot and a flaming torch passed between the pieces, symbolizing God Himself making the covenant (Genesis 15:17).

3.2. Establishing Circumcision as a Sign

• God specified that Abraham would have a son through Sarah:

  “I will bless her and give you a son by her. I will bless him, and he shall be a blessing” (Genesis 17:16–19).

• This reaffirmed the promise of descendants and the continuation of the covenant through Isaac.
