Luther on what the Bible is about:
[H]e who would correctly and profitably reads Scripture should see to it that he finds Christ in it; then he finds life eternal without fail. On the other hand, if I do not so study and understand Moses and the prophets as to find that Christ came from heaven for the sake of my salvation, became man, suffered, died, was buried, rose, and ascended into heaven so that through him I enjoy reconciliation with God, forgiveness of all my sins, grace, righteousness, and life eternal, then my reading in Scripture is of no help whatsoever to my salvation.
I may, of course, become a learned man by reading and studying Scripture and preach what I have acquired; yet all this would do me no good whatever.
