The phrase “render to Caesar the things that are Caesar’s, and to God the things that are God’s” which Jesus spoke in Luke 20:25 is likely a familiar one. I had a friend in college who worked at Little Caesar’s pizza, and he showed up at Bible study with some pizza from there one night. We had agreed to split the cost, so when he walked in he said “render unto Caesar!” We all got the reference and a couple of us laughed (I admit one of them was me).
The “render to Caesar” saying comes from a time where some scribes and chief priests tried to get Jesus in trouble, as they often did, trying any means necessary to condemn Him. In this case, they first flattered Jesus, trying to catch Him off-guard, then asked Him, “Is it lawful for us to give tribute to Caesar, or not?” They thought if Jesus said yes, it would upset the Jews who wanted their Messiah to overthrow Rome, and that if He said no, it would upset the Romans and perhaps they would arrest Jesus as a revolutionary. They thought they had Him trapped, but His answer quoted above was unexpected by them, yet truthful and insightful.
Often the lessons taken from this story have to do with Jesus’ ability to thwart the attempts of His enemies to catch Him in His words, or with the Christian’s obligation to pay taxes, or with something about the relationship between the Jews and Rome. There are several good applications.
Another important application that’s key to the story, can be highlighted if we shorten the saying to “render…to God the things that are God’s.” This last part of the quote is where Jesus subtly tells those trying to catch Him that they weren’t giving to God the things they should be. Although they were the religious leaders of their day, they were focused on the wrong things, like their money and their resentment against the government. Or even their obsession with arguing with Jesus.

What are the things that are God’s and that we should render to Him?
Paul helps answer this in Romans 12:1, which says “I appeal to you therefore, brothers, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship.”
Here Paul says that the thing we should be rendering to God is our very selves, and Jesus implied this when He said “render…to God the things that are God’s.” This answer said to the Jews, and everyone listening, that their Messiah wasn’t only going to overthrow Rome, but He was going to overthrow all kingdoms, including those we build in our own hearts and minds. From an eternal perspective, the many flaws of Roman rule under which the first-century Jews lived were minor inconveniences, including the paying of taxes and other, real abuses. Jesus wants us to focus on the real challenge: what to do about mankind’s rebellion from God? This is the real mission of the Messiah.
Luke follows the “render to Caesar” story with a question some Sadducees asked Jesus about the resurrection, also to try and catch Him saying something wrong. The story was not put there by accident, but in the sequence, I think we see that there is in fact a resurrection, and that our resurrected selves will be much different than our current selves. Our new selves will be able to perfectly worship God, and we will be able to fully offer our “bodies as a living sacrifice” while we can only do so imperfectly now.
In the meantime, we don’t get a free pass to do what we want because we aren’t perfected yet. Every day and every moment, we are to “render…to God the things that are God’s” in ways the religious leaders of Jesus’ day (as well as the audience of most of the Old Testament prophets) failed to do.
In closing, I’ll quote the OT prophet Micah, who differentiated between the animal sacrifices of ancient Israel from the “living sacrifice” God requires:
“With what shall I come before the LORD,
and bow myself before God on high?
Shall I come before him with burnt offerings,
with calves a year old?
Will the LORD be pleased with thousands of rams,
with ten thousands of rivers of oil?
Shall I give my firstborn for my transgression,
the fruit of my body for the sin of my soul?”
He has told you, O man, what is good;
and what does the LORD require of you
but to do justice, and to love kindness,
and to walk humbly with your God?” (Micah 6:6-8)
Today, “render…to God the things that are God’s.”
