Nor are they merely calculated to instruct, but also to cheer and inspire. There is scarcely another power that will ease the heart, strengthen and sustain the lagging and downcast spirit, as will a heartfelt "Commit whate'er may grieve thee," and kindred hymns. In the darkest moments of his life, David tuned his harp and bade sorrow and grief flee. In Philippi's dungeon, at the hour of midnight, Paul and Silas raised their voices in melody of praise. After days of bitter conflict and labor the Reformer would produce his lute, and sing unto the Lord a pleasant song, to the joy of the angels and the chagrin of the devil. Gustavus Adolphus, Sweden's valiant hero of the faith, who fought and died for religious liberty, never entered a battle without prostrating himself with his army before the Lord of heaven and singing, "A Mighty Fortress Is Our God," "Fear Not, O Little Flock, the Foe." Sacred story tells us of Saul, that whenever the evil spirit came over him, the king would send for David, and under his tune find relief from his torments. Nor has the spiritual song lost any of this soothing element. "The singing of songs and hymns purifieth our thoughts," says a church-father, "represses sensuality, stirs the heart to pure emotions, awakens a love and a longing for the beauty of holiness, moves to holy contrition and godly sobriety." No wonder that Luther ranked music next to theology of pure religion, effectual as it is in warding off Satan's suggestions, and aiding us in becoming better and more noble, and hence, in harmony with this Sunday, Cantate, we are justified in bringing this topic to your consideration, especially in our times, which are replete with so much vain and shoddy music, senseless and overwrought travesties, often set to tunes that are a perfect scandal and shame upon all divine worship, and better suited for the opera than for the house of God. Let us rejoice in this good gift God has bestowed upon us, and diligently use it in our churches and homes until it shall be our happy lot to join the multitudes of those who shall raise their voices to pour forth their everlasting song, and cause the city of God to ring with anthems of perpetual worship. Amen. FIFTH SUNDAY AFTER EASTER. Praying always with all prayer and supplication in the Spirit, and watching thereunto with all perseverance.--_Eph. 6, 18._
