A Christian's life is so fraught with danger that it is just as if the believer were walking up a narrow mountain track or even worse, as if he were walking on a knife-edge. The Devil is prowling amongst us in this world, constantly seeking to devour us, so that we might lose our patience, and fall into despair and into rebellious grumbling against God. In addition, the world acts against our own interests by unyieldingly opposing our journey to heaven. In a similar way, our flesh is a heavy burden which oppresses us on all possible sides. Moreover, the path itself is so narrow that there is enough trouble to follow this path, even if there were no additional perils and obstacles. Nevertheless, we must pull through or we will otherwise fall prey either to the World or to the Devil. So you must ponder on these things and act accordingly. If you really want to be a Christian, then become one, because there is no other way. (...) Whatever, you will, at least, not make the path any broader.
Schriften, 32. Band., S. 502
