As children, our clothing was not so much a reflection on us as it was on our parents.  After all, they were supposed to be the ones in charge.  As children of God, our conduct serves as that outer layer that the world sees.  Our physical clothing might communicate something of that, but our character should be above reproach.  Paul uses this metaphor in Colossians 3:12-17, making it clear that we must make a choice.  A few verses earlier we are told that if we are in Christ,we have laid aside the old self and put on the new.  We’re to throw out those filthy old clothes and put on the clean, new, holy ones that He has give to us.  We begin to take on His character and to look like Him.
