“There is,” he said, “ a believing about God. You believe that what is said about God is true.” But with that passive sort of believing, you have no idea how powerful real faith can be. “Real faith,” he said, “is a lively, reckless, act of confidence in God’s grace. It is so vital and powerful, it kills the past and reconstitutes us, entirely new men in heart, in mind, in faculties, with the will and the impulse to do good works.”
What Luther said is true today. Faith is believing so hard, I take some action. If enough of us believe enough—each in the things we know in our hearts are truly good—and if we act as best we can, then I believe it can make more difference than we even dare to dream.
