After Abraham demonstrated his willingness to sacrifice Isaac in obedience to God, the Lord promised that in Abraham’s “seed” all nations would be blessed. This “seed” is a reference to the Messiah that would be born to Abraham’s line. The apostle Paul explained this verse: “Now to Abraham and his Seed were the promises made. He does not say, ‘And to seeds,’ as of many, but as of one, ‘And to your Seed,’ who is Christ” (Gal. 3:16). This is the “Seed” of the woman that would crush the serpent’s head (Gen. 3:15). This is the “Seed” that would come as the Lamb of God, sent to take away the sins of the world. This is Christ.
The entire Bible, from beginning to end, was written that we might hear and believe the good news about Christ. He is the promised Seed. He is the Lamb of God. Jesus Christ is Savior and Lord.
