Eunice McGarrahan gave an inspiring talk on Christian discipleship in which she said, “A costume is something you put on and pretend that you are what you are wearing. A uniform, on the other hand, reminds you that you are, in fact, what you wear.”

Her comment sparked memories of my first day in US Army basic training when we were each given a box and ordered to put all our civilian clothes in it. The box was mailed to our home address. Every day after that, the uniform we put on reminded us that we had entered a period of disciplined training designed to change our attitudes and actions.

“Cast off the works of darkness,” the apostle Paul told the followers of Jesus living in Rome, “and . . . put on the armor of light” (Rom. 13:12). He followed this with the command to “put on the Lord Jesus Christ, and make no provision for the flesh, to fulfill its lusts” (v.14). The goal of this “casting off” and “putting on” was a new identity and transformed living (v.13).

When we choose to follow Christ as our Lord, He begins the process of making us more like Him each day. It is not a matter of pretending to be what we aren’t but of becoming more and more what we are in Christ.
