Stanza 1 expresses the message of Psalms 96-100.
When stanza 1 speaks of the fact that ”God will dwell among us”, we hear reference to Immanuel from Isaiah 7:14 and Matthew 1:20-23.
Stanza 2 speaks of the day when “mountains will shake and worthless idols will fall”. See Matthew 24:26-31, Luke 21:20-28, and II Peter 3:10-13.
“Former lamentations now are songs of peace,” stanza 3 of the song says. This hopeful joy in Christ’s coming is found in Our Song of Hope, stanza 1: “God is the world’s true Hope,” and therefore “we are a people of hope” (stanza 1), “Jesus Christ is the hope of God’s world” (stanza 4), and it even makes clear that “our ascended Lord gives hope for two ages”—in the age to come and in this age (stanza 5).
