Young men, in the same way be submissive to those who are older. All of you, clothe yourselves with humility toward one another, because, "God opposes the proud but gives grace to the humble." 1 Peter 5:5
Humility is the appropriate "attire" for the follower of Jesus. The lasting principle, quoted here by Peter, makes the case that God "sets himself against" the proud, but gives grace to those who live in humility (Proverbs 3:34).
The instruction to "clothe yourselves" refers to a slave who puts on an apron before serving. Peter may have chosen this word as he reflected back on that day when Jesus "wrapped a towel around his waist" and washed the feet of the disciples. Peter resisted this act of service until Jesus said, "Unless I wash you, you have no part with me." "Then, Lord," Simon Peter replied, "not just my feet but my hands and head as well!" (John 13:8-9).
Humility is the appropriate attire of every believer and here's the way to attain it. C. S. Lewis wrote, "If anyone would like to acquire humility I can ... tell him the first step. The first step is to realize that one is proud. And a biggish step, too. At least, nothing whatever can be done before it. If you think you are not conceited, it means you are very conceited indeed."
Father, we are proud and conceited. Our first thought is always about ourselves. So we confess our pride to You. Forgive us and make us people who are willing to wear the apron of humility everywhere every day. In Jesus' name. Amen.
