Final answer:
After original sin, God made a promise to restore our relationship with Him by sending a Redeemer, as mentioned in Genesis 3:15.
Step-by-step explanation:
According to religious beliefs, after the original sin, God made a promise to restore our relationship with Him by saying, "I will send a Redeemer." This promise is found in the Bible, specifically in Genesis 3:15 where God tells the serpent, "And 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 prophecy refers to Jesus Christ, who would eventually come to redeem humanity from sin and restore their relationship with God.
