Lord, for tomorrow and its needs I do not pray; Keep me, my God, from stain of sin, just for today. Let me no wrong or idle word unthinking say; Set Thou a seal upon my lips, Father, today.
Let me both diligently work, and duly pray; Let me be kind in word and deed, Father, today. Let me in season, Lord, go forth, in season stay; Let me be faithful to Thy grace, dear Lord, today.
Let me be slow to do my will, swift to obey; Help me to sacrifice myself gladly today. So for tomorrow and its needs I do not pray; Still keep me, guide me, love me, Lord, through each today.
