Give to Caesar

"Give to Caesar what belongs to Caesar, and give to God what belongs to God" (Mark 12:17)

When Jesus asked whose image was on the coin, He pointed to the image as a sign of ownership.  Caesar's image and inscription on the coin meant that it belonged to Caesar.  Jesus applied this logic and expression of ownership to humanity, when He added: "Give to God what belongs to God."
    Going by the logic of the comparison, if the coin belonged to Caesar because it bore the image and inscription of Caesar, then humanity created in the "image and likeness of God" (Gen 1:26-27) must belong to God.  If the coin must be given to Caesar because it bore Caesar's sign of ownership, namely his image, then we as human beings, bearing God's sign of ownership in our creation in the image of God, must in justice give ourselves to God. 
    That means that religion and worshiping God are about justice.  Giving ourselves to God is doing what is just: We are giving to God what belongs to God.  The worship of God is a basic act of justice.
    When we don't give to God what belongs to God, we are not able to give to others what belongs to them.  When we are unjust to God, we will be unjust to others.  The less religious we become, the more the world will be filled with unjustice, and the more faithful we become in relationship with God, the more justice there will be in the world.
