This Easter hymn pictures Christ's death as the final battle with the powers of evil, but Christ is the victor; his resurrection marks the decisive outcome of that battle. Each stanza begins with some aspect of Christ's resurrection and moves to our response of praise. A poetic commentary on and summary of Paul's resurrection discourse in 1 Corinthians 15, the entire text is framed with "alleluias" (like some of the psalms).

In addition, Our Song of Hope, stanza 5 professes: “On the day of the resurrection, the tomb was empty; His disciples saw Him; death was defeated; new life had come. God’s purpose for the world was sealed.”
