Mat 22:21 Render therefore unto Caesar the things which are Caesar's; and unto God the things that are God's.

I think of this line whenever I happen upon a religious show on television that goes on endlessly about how important it is spiritually to give money to their ministry and how God would bless you for doing so. Here, Christ makes it clear that money is not God's concern or what we should be sacrificing to God.

This raises the question, if money is a thing of Caesar, that is, society, what are the things that Christ says we need to give God?

The answer can be found in the previous parable. He wants us to answer God's call and respect his messengers (angelos, in Greek) and care about our relationship with God. The physical, mental, and emotional parts of our lives are all His gifts, but we cannot get stuck in any of them. One must lead to the other and all come from and lead to the spiritual: the pure relationship in which we see God in everything. He wants us to avoid the mistake of getting stuck in one part of life, so we cannot go onto the next part of life.

"Render" is from apodidômi, which means "to give back," "to restore," and "to deliver." It has the economic sense of "to sell" or "to give something for one's own profit."
