What does Genesis 15 teach us about God's covenant?

Genesis 15 demonstrates God's unwavering commitment to His covenant with Abram, showcasing the grace extended to humanity. In this chapter, God reassures Abram, promising descendants despite Abram's doubts due to his and Sarah's old age. The Lord's declaration that 'so shall thy seed be' signifies not just physical descendants but also the promise of redemption through Christ. This covenant reflects the larger theme of God's desire to have a people for Himself, emphasizing that the covenant is grounded in His grace and purpose, not human merit.
