Battle Cry of the Faith

"In the present situation the Christian life emerges as a life under the cross. The struggle for faith does not take place prior to conversion as in much of non-Lutheran Protestantism, it commences with the kindling of faith. And so, in the Lord's Prayer, we pray for faith against unfaith. In this way the Lord's Prayer has a way of bringing a deep comfort to people battling with an abiding sense of their own unbelief. In the Lord's Prayer, the Christian prays for faith to receive the blessings enumerated by the Creed and prays against Satan who would undermine faith by depriving the Christian of Christ's blessings."
