It does not however become us to seek by our prayers bodily afflictions. For Christ has universally commanded men every where to pray that they enter not into temptation. But when one has already entered, it is fitting to ask from the Lord the power of enduring, that we may have fulfilled in us those words, He that endureth to the end shall be saved. (Mat. 10:22.)
