1. O God of light, Your Word, a lamp unfailing, Shall pierce the darkness of our earth bound way And show your grace, Your plan for us unveiling, And guide our footsteps to the perfect day. 2. From days of old, through blind and willful ages, Though we rebelled, You gently sought again, And spoke through saints, apostles, prophets, sages, Who wrote with eager or reluctant pen. 3. Undimmed by time, those words are still revealing To sinful hearts Your justice and Your grace; And questing mortals longing for Your healing, See Your compassion in the Savior's face. 4. To all the world Your summons You are sending, Through all the earth, to every land and race, That myriad tongues, in one great anthem blending May praise and celebrate Your gift of grace.
