Living by Faith Is Not Easy in This Fallen World

'Luther captured, perhaps better than any theologian, the weakness that still bedevils our lives. He says, “The words ‘freedom from the wrath of God, from the Law, sin, death, etc.,’ are easy to say, but to feel the greatness of the freedom and to apply its results to oneself in a struggle, in the agony of conscience, and in practice — this is more difficult than anyone can say.”  Living by faith is not easy in this fallen world.'
