What did God mean in the Bible when he said he will make your enemies your foot stool?
This phrase comes from Psalm 110:1, the beginning of a messianic Psalm. Messianic psalms are psalms that are promises from God for Jesus, the Messiah. So the “your” in the Psalm refers to Jesus. This Psalm is all about the protection and reign of Jesus after he has completed his mission.
It depicts the coronation of the Messiah, his establishment on his throne. This is further confirmed by the reference to Melchizedek, the priest of Salem (Psalm 110:4). The author of Hebrews talks about how Jesus fulfills that rule perfectly (Genesis 14:18-20; Hebrews 7:1-11).
Making Jesus’ enemies a footstool for his feet means that God will subject his enemies to him. He will be above them. In a sense, he will be able to walk all over them. They will have no choice but to acknowledge his kingship.
It is God who decides the King he will choose. Out of all the kings of the nations, he will choose Jesus. But Jesus will be the perfect King. No King comes close to him and all the qualities God is looking for.
Psalm 110:5-7 explains that God decides whom his kingdom will be. He chooses the Messiah over all the kings of the nations. And he lifts up his head to be the chosen king, Jesus the King of Kings and Lord of Lords.
