Final answer:
The first promise of the gospel, or the Protoevangelium, is recorded in Genesis 3:15, foretelling the coming Messiah's victory over evil, which is fulfilled in Jesus Christ.
Step-by-step explanation:
The first promise of the gospel, often referred to as the Protoevangelium, is found in Genesis 3:15. This scripture is considered by many Christian theologians to be the first indication of God's plan for redemption following the fall of Adam and Eve.
In this verse, God speaks to the serpent and says, "I will put enmity between you and the woman and between your offspring and hers; he will crush your head, and you will strike his heel." This is interpreted as the promise that the Messiah would come and ultimately defeat evil, symbolized by the serpent. This prophecy points towards Jesus Christ's victory over sin and the establishment of God's kingdom through His sacrifice.
