The text contrasts the changing character and frailty of human life with the everlasting love of our changeless God. Though "life's dangers overwhelm us," we have confidence in God's guidance and protection. The text helps us to give voice to our own trust in divine providence, to bring comfort to those in distress, and to express our hope for "everlasting peace."
Psalter Hymnal Handbook
In the passage of time, the child of God lives with expectancy—for God to renew them and for God to lead them in obedience (Our Song of Hope, stanza 9).
Even though time passes and years end swiftly, God is eternally faithful. And so God’s children testify using the words of Our World Belongs to God, paragraph 1: “As followers of Jesus Christ, living in this world—which some seek to control, and others view with despair—we declare with joy and trust: Our world belongs to God!”
