By Martin Luther

      Paul deplores the fact that it is difficult for the mind to retain a sound and steadfast faith. A man labors for a decade before he succeeds in training his little church into orderly religion, and then some ignorant and vicious poltroon comes along to overthrow in a minute the patient labor of years. By the grace of God we have effected here in Wittenberg the form of a Christian church. The Word of God is taught as it should be, the Sacraments are administered, and everything is prosperous. This happy condition, secured by many years of arduous labors, some lunatic might spoil in a moment. This happened in the churches of Galatia which Paul had brought into life 24in spiritual travail. Soon after his departure, however, these Galatian churches were thrown into confusion by the false apostles.

      The church is a tender plant. It must be watched. People hear a couple of sermons, scan a few pages of Holy Writ, and think they know it all. They are bold because they have never gone through any trials of faith. Void of the Holy Spirit, they teach what they please as long as it sounds good to the common people who are ever ready to join something new.

      We have to watch out for the devil lest he sow tares among the wheat while we sleep. No sooner had Paul turned his back on the churches of Galatia, than the false apostles went to work. Therefore, let us watch over ourselves and over the whole church.
