Of the library of 110 volumes of which Luther is the author, 85 of them treat of the Bible and expound its pure evangelical teachings in commentaries, sermons and catechetical writings. He popularized the word evangelical. With his tongue and pen he labored incessantly for the evangelization of Europe. That Europe is evangelized is due more to his labors and writings than to those of any other. What those writings did for Europe they may do, and we believe, will do, for the world in a greater or less degree. The greatest evangelist of Europe has a God-given place in the evangelization of the world. His most evangelical classics should be translated into all the dialects of earth as soon as the Bible is given to the people in their native tongue. Dr. Warneck says: "By the Reformation the christianizing of a large part of Europe was first completed, and so far it may be said to have carried on a mission work at home on an extensive scale." Further he says: "The Reformation certainly did a great indirect service to the cause of missions to the heathen, as it not only restored the true substance of missionary preaching by its earnest proclamation of the Gospel, but also brought back the whole work of missions on Apostolic lines. Luther rightly combats, as Plitt insists, 'the secularizing of missionary work.'" In explaining the 117th Psalm Luther says: "If all the heathen shall praise God, he must first be their God. Shall he be their God? Then they must know him and believe in him, and put away all idolatry, since God can not be praised with idolatrous lips or with unbelieving hearts. Shall they believe? Then they must first hear his Word and by it receive the Holy Spirit, who cleanses and enlightens their heart through faith. Are they to hear his Word? Then preachers must be sent who shall declare to them the Word of God." So in his familiar hymn, "Es wolle Gott uns gnaedig sein." "And Jesus Christ, His saving strength To Gentiles to make known, That thee, O God, may thank and praise The Gentiles everywhere." In commenting on the words of the Second Psalm, "Ask of me and I will give thee the heathen for thine inheritance," Luther says: "Christ, therefore, being upon earth and appointed king upon Mount Zion, receives the Gentiles who were then promised unto him. The words 'of me' are not spoken without a particular meaning. They are to show that this kingdom and this inheritance of the Gentiles are conferred on Christ, not by men, nor in any human way, but by God, that is, spiritually." All who retain the good old custom of the fathers in reading Luther's Postil sermons on the Gospel and Epistle texts for each Sunday know what deep missionary thoughts are found in the sermons for Epiphany, Ascension Day and Pentecost.
