Although Jesus' enemies have been made His footstool, His feet are depicted throughout the Bible as being bruised by the enemy when fighting to redeem us. This metaphorically is a picture of the fact that Jesus did not just come into the world and defeat the enemy without suffering, but He paid a price and suffered on our behalf before gaining victory over the enemy. So when the Bible shows Jesus as having "bruised" or "fire-emblazoned" feet, this is the picture that the Word of God is painting.
Let me show you what I mean:
EXAMPLE 1- In Genesis 3 Satan is punished for tempting Adam and Eve and causing them to sin. His punishment, shown in Genesis 3:15, tells that God will send a Seed (Jesus) whose heel Satan will "bruise", but He let's Satan know that ultimately he will be placed under the Seed's feet:
Verse 15: And I will put enmity Between you and the woman, And between your seed and her Seed; He shall bruise your head, And you shall bruise His heel.
We know this scripture is referring to Jesus as the Seed because any noun in the Bible that is written with a capital letter is used to represent God, Jesus or some other form of God. (We also know Jesus to be the seed that God promised as a descendant of Abraham: And in thy seed shall all the nations of the earth be blessed -Genesis 22:18).
Now in the above scripture, God is telling Satan that Jesus will bruise his head, but that Satan will bruise Jesus' feet. This is the first time Jesus' feet are mentioned in the Bible. However, throughout the Bible His feet are constantly being referred to as being scorched, bruised, etc. by the enemy. This, once again, is a metaphor that even though Jesus gained victory for us, it was not a victory gained without a cost. He suffered on our behalf and was "bruised for our iniquities". Hence the God's saying to Satan "And you shall bruise His heel".
EXAMPLE 2- In Revelation 1:15 when the Apostle John first receives a vision of the "Son of Man" (Jesus) he describes His feet in this way:
Verse 15: And his feet like unto fine brass, as if they burned in a furnace;
Here Jesus, the Perfect Son of God, is once again seen as having flawed feet. This time His feet are described as being burned in a furnace. This metaphorically paints the same picture that Jesus suffered on our behalf, considering he went to hell after dying and before raising from the dead. Hence, the reference towards being burned. Jesus' feet are depicted as burned in reference to the suffering He went through for us after His death.
EXAMPLE 3- The idea that the enemy will be placed under Jesus' feet poetically means that they will be below Jesus or that Jesus will be above His enemies. This is why Jesus' feet are the part of Him that is shown as being at war with the enemy:
25 For he must reign, till he hath put all enemies under his feet.
26 The last enemy that shall be destroyed is death. ( 1 Cor. 15: 25-26)
The Lord said unto my Lord, Sit thou on my right hand,
43 Till I make thine enemies thy footstool. (Luke 20: 42-43)
EXAMPLE 4- So why worship at the feet of Jesus? A person who truly knows the value of Jesus' sacrifice for them metaphorically would appreciate Jesus' feet. It is Jesus feet that are portrayed almost as the weapon that defeats the enemy, being bruised in the process.
If you read the story in Luke 7:37-50 when a woman who is publicly known as a sinner begins to wash Jesus' feet with her tears, dry His feet with her hair, kiss His feet and anoint His feet with oil, this is not merely an act of humility. It is an acknowledgement of the fact that (metaphorically speaking) Jesus' feet are bruised because of HER; because she is a great sinner and Jesus' feet were bruised on behalf of our sinfulness. So much so, as a religious man stands nearby and questions why Jesus has a sinner tending to His feet, Jesus answers and says, This woman loves me much because she knows she is forgiven much. Her actions at His feet showed that she had been made aware of Jesus' purpose to come into the world and die on behalf of the unrighteous.
SO why worship at Jesus feet? Had we been perfect, it would not have been a battle for Jesus' enemies to be made His footstool. But because our sins could not go unpunished Jesus had to suffer before allowing us to reap the benefits of a person who has no sin; healing, prosperity, peace, etc. Jesus had to suffer in order for us to redeem those rights and in order for His enemies to efficiently be placed under His feet for our benefit. There was a mighty sacrifice and price that needed to be paid on our behalf. For this reason, we worship at Jesus' feet........... because we know we are FORGIVEN MUCH!
