Then the Pharisees went off and discussed how they could trap Jesus in argument. Eventually they sent their disciples with some of the Herod-party to say this, “Master, we know that you are an honest man who teaches the way of God faithfully and that you don’t care for human approval. Now tell us—‘is it right to pay taxes to Caesar or not’?”
But Jesus knowing their evil intention said, “Why try this trick on me, you frauds? Show me the money you pay the tax with.” They handed him a coin, and he said to them, “Whose face is this and whose name is in the inscription?”
“Caesar’s,” they said.
“Then give to Caesar,” he replied, “what belongs to Caesar and to God what belongs to God!”
This reply staggered them and they went away and let him alone. (Matt. 22:15-22)
Isn't Jesus absolutely brilliant?
In the space of one action, one question and one comment, He is simultaneously doing three separate things: He is lowering the valuation of any-currency-ever as the denominator of life's importance; He is heightening our understanding of what our lives owe to God: ie. EVERYTHING; and, by so casually saying, "Just pay the tax," and then following that up with "And give God your all," He is showing us what the life of following Him is supposed to look like: stealthy, under-the-radar, seeming-to-fit-in while, in reality, it's working to aid and abet another Kingdom's earthly invasion!
He is setting up, here, a sort of Kingdom of Heaven guerrilla warfare. It will seem to be everywhere and yet nowhere. It will look just fine to the Caesars of this world - but they'll have no idea what's coming; Who is with us, behind us...
