But put on the Lord Jesus Christ, and make no provision for the flesh, to gratify its desires.” (Romans 13:14, ESV)

Paul tells followers of Jesus to “put on the Lord Jesus Christ.”  What does he mean?

One thing we absolutely know is that putting on the Lord Jesus Christ is the opposite of gratifying the desires of the flesh.  John will write later:

For all that is in the world—the desires of the flesh and the desires of the eyes and pride of life—is not from the Father but is from the world.” (1 John 2:16, ESV)

Desires here is the same word that Paul uses [ἐπιθυμία for Greek studs]. So putting on Christ is the opposite of putting on the desires of the flesh.

Putting on the Lord Jesus Christ would seem to be to take on his character, conduct, and attitudes.  This is why it is so important to saturate ourselves in the gospels because it is in those four books that we come to understand Christ as we watch him interact with people, as we hear him preach, as we see him heal diseases and cast out demons.  Certainly Paul must have been thinking about what it means to put on Christ when he wrote to the Galatians:

I have been crucified with Christ. It is no longer I who live, but Christ who lives in me. And the life I now live in the flesh I live by faith in the Son of God, who loved me and gave himself for me.” (Galatians 2:20, ESV)

Put off our fleshly desires.  Put on Christ.  Live by faith in the Son of God.  It seems so easy, but of course we will be working at it our entire lives because one thing is for sure, none of us understands how deep our fleshly desires go and how difficult it is to root them out.
