When?

If I were told that I must die to-morrow,     That the next sun     Which sinks should bear me past all fear and sorrow     For any one,     All the fight fought, all the short journey through:     What should I do?     I do not think that I should shrink or falter,     But just go on,     Doing my work, nor change, nor seek to alter     Aught that is gone;     But rise and move and love and smile and pray     For one more day.     And, lying down at night for a last sleeping,     Say in that ear     Which hearkens ever: "Lord, within Thy keeping     How should I fear?     And when to-morrow brings Thee nearer still.     Do Thou Thy will."     I might not sleep for awe; but peaceful, tender,     My soul would lie     All the night long; and when the morning splendor     Flashed o'er the sky,     I think that I could smile--could calmly say,     "It is His day."     But, if instead a hand from the blue yonder     Held out a scroll,     On which my life was, writ, and I with wonder     Beheld unroll     To a long century's end its mystic clew,     What should I do?     What COULD I do, O blessed Guide and Master,     Other than this:     Still to go on as now, not slower, faster,     Nor fear to miss     The road, although so very long it be,     While led by Thee?     Step after step, feeling Thee close beside me,     Although unseen,     Through thorns, through flowers, whether the tempest hide Thee,     Or heavens serene,     Assured Thy faithfulness cannot betray,     Thy love decay.     I may not know, my God; no hand revealeth     Thy counsels wise;     Along the path a deepening shadow stealeth,     No voice replies     To all my questioning thought, the time to tell,     And it is well.     Let me keep on, abiding and unfearing     Thy will always,     Through a long century's ripening fruition,     Or a short day's.     Thou canst not come too soon; and I can wait     If thou come late.
