Final answer:
In Christian theology, the phrase "bruise Satan's head" refers to the promise in Genesis that a descendant of Eve would defeat Satan, a promise fulfilled through Jesus Christ. By his crucifixion and resurrection, Jesus conquered sin and death, and dealt a decisive blow to Satan's power.
Step-by-step explanation:
In Christian theology, the phrase "bruise Satan's head" is a reference to the prophetic promise of God that a descendant of Eve would ultimately defeat the power of Satan. This promise was fulfilled through the person of Jesus Christ. In the Bible, Jesus is described as the one who conquered Satan and his works through his death and resurrection.
One of the key biblical texts that speaks to this is found in Genesis 3:15, where God addresses the serpent (Satan) and says, "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 verse is often referred to as the protoevangelium or the first gospel because it foreshadows the coming of Christ as the Savior who would defeat Satan.
By his crucifixion and resurrection, Jesus not only conquered sin and death but also dealt a decisive blow to Satan's power. The imagery of bruising Satan's head signifies the defeat and destruction of Satan's dominion over humanity.
