Pilgrimage is a much-used metaphor in Williams's texts. "Guide Me, O My Great Redeemer" draws on images from the Exodus story in the Old Testament: "bread of heaven" (Ex. 16), "crystal fountain" (Ex. 17), "fire and cloudy pillar" (Ex. 13:21-22). But the New Testament, Christocentric focus of the text is equally clear in the repeated final line of each stanza: Jesus is the "bread of heaven" (or "bread of life," (John 6), the "rock" who is our "strength and shield" (1 Cor. 10:4), and the victor over "death … and hell's destruction" (Rev. 1:18). Thus the change from the original “Jehovah” of the first line to "Redeemer" makes eminent sense.
Psalter Hymnal Handbook
The journey of the Israelites through the wilderness is a picture of God’s children as pilgrims on a long and sometimes difficult journey. Yet, through everything God has a plan, which is revealed in the unfolding of the covenant. Our World Belongs to God, paragraph 33 testifies about a “story of God’s mighty acts in the unfolding of covenant history.” This unfolding of the covenant plan is a testimony, according to Our World Belongs to God, paragraph 18, of “the long road of redemption” for the Israelites and for God’s children living today.
