Ah, Lord unto whom all hearts are open, Thou canst govern the vessel of my soul far better than I can. Arise, O Lord, and command the stormy wind and the troubled sea of my heart to be still, and at peace in Thee, that I may look up to Thee undisturbed, and abide in union with Thee, my Lord. Let me not be carried hither and thither by wandering thoughts; but, forgetting all else, let me see and hear Thee. Renew my spirit; kindle in me Thy light, that it may shine within me, and my heart may burn in love and adoration towards Thee. Let Thy Holy Spirit dwell in me continually, and make me Thy temple and sanctuary, and fill me with divine love and light and life, with devout and heavenly thoughts, with comfort and strength, with joy and peace—Amen.

Johann Arndt (1555–1621).
