Armour appears an antiquated word. We think of medieval knights riding to war, on horseback. In reality the word is still current as in the body armour police wear, offering them protection against assault. Paul invites us to take our discipleship seriously. The devil has one purpose which is to destabilise and misdirect us from our chosen goal: to follow Jesus. It’s the reason we are so easily distracted from our good intentions to pray. Here we enter the shallows of the warfare to which we are called by God.
