Luther and Lewis

For our Gospel and deeds are not founded upon us, neither are they for our sakes, but everything is for the sake of this Lord Christ, from whom we have all things and for whose sake we preach, and live, and suffer. Since, then, all things are for His sake, we leave the caring to Him who says that He will bring all these things to fulfillment and give us the spirit and courage we need.—Martin Luther, Exposition, Jn xiv, xv.

The central point of the Christian belief is that Christ’s death has somehow put us right with God and given us a fresh start. Theories as to how it did this are another matter. A good many different theories have been held as to how it works; what all Christians agree on is that it works.—C. S. Lewis, Business of Heaven, p. 265.
