Armour of God Game
Bible ref: Ephesians 6.
To prepare for this, print out a picture of each item of the armour of God for each child.(I'll put some on here soon.) To play the game, give each child a picture of each piece of armour. Then you shout words and they hold up the corresponding piece of armour, e.g. "RIGHTEOUSNESS!" and the kids have to hold up the breastplate. Shout "SALVATION!" and the kids hold up the helmet. Shout "WORD OF GOD!" and they hold up the sword and so on.
This is good if you're teaching the kids that memory verse, and also great fun.
