A light switch is a pretty simple device. Either the switch is flipped and causes the circuit to be completed and provide power to the device or it is set the opposite way and the circuit is open and no power can go. There is no in between for the switch. Pastor John Samuel Barnett shows us that with the call to put on God’s armor that Christians are like a light switch. We are either standing against the tide of darkness and the attacks of the evil one or we fall into darkness. There are no sediment Christians. We should choose to stand in the power and armor of God’s gracious gifts.
