After the discourse, a hymn in direct didactic relation to it may be sung in a bright and joyous spirit: “God is love; His mercy brightens All the path in which we rove.” The postlude will be tenderly joyous and sympathetic in style. There are many preachers whose nervous organizations would not enable them to adjust themselves to so tender an emotional key in developing the service. On the other hand, many congregations would not follow it, but would be lulled to sleep by it. _b._ Joyful Service. They would be entirely right in selecting as the opening hymn one of general praise and worship: “Come, Thou Almighty King, Help us Thy name to sing, Help us to praise”; or even the quietly majestic hymn, “Holy, holy, holy, Lord God Almighty! Early in the morning our song shall rise to Thee.” The second hymn may be more prayerful and tender: “Guide me, O Thou great Jehovah, Pilgrim through this barren land,” or “When all Thy mercies, O my God, My rising soul surveys.” The final hymn may be more didactic: “God is the refuge of His saints, When storms of sharp distress invade”; or the more stirring and forceful “Give to the winds thy fears; Hope, and be undismayed”; or that wonderful paean of faith in the divine love and providence, “How firm a foundation, ye saints of the Lord, Is laid for your faith in His excellent word.” In this case the postlude will be bright and joyous, preferably with some soft and tender episodical passages. _Hymns for a Missionary Service._ The preacher plans a missionary discourse: what is his order of service to be? That means an aggressive, spiritual program whose purpose is stimulation of enthusiasm, of courage, of conquering faith, of bold decision. The organist will be asked to play a bright prelude with pronounced but dignified rhythm, and striking harmonic progressions. The anthem by the choir may be based on some text of praise from the Psalms with stirring, somewhat rhythmical music that will stimulate the nerves of the people rather than soothe them. The responsive reading should be a Psalm of triumph, say the ninety-sixth. The long prayer for once may drop out of the omnibus conventionality and lead the people in magnifying the irresistible power and the conquering love of God, with enough reference to current sorrows in the congregation to serve as a contrast, to make the realization of the strong right arm of God more vivid. The hymns should be in keeping with this joyous recognition of God’s invincibility and assured triumph. The first hymn may be Charles Wesley’s “Oh, for a thousand tongues to sing.” This is worship—mingled with faith and with aggressive purpose, it is true, but nevertheless distinctly worship.
