Play dress up with your child. Encourage them to practice the snaps, zippers, and buttons by themselves, and as you play together, talk about how God clothes us with His armor in the same way we get dressed. If you have a child who doesn't want armor, talk about how God clothes us with His beauty every morning.
God has a purpose for everything.
Button, snap, and zip clothing.
Put on the full armor of God. . .
Ephesians 6:11 (NIV)
