The Young Man is an agitated listener sitting through a church service. Annoyed by teachings that treat human existence as a mere waiting period for the afterlife, his internal monologue forms the core of the poem. He views the world as a broad field of battle and advocates for heroic, purposeful action in the present moment. Rather than submitting to despair, he actively seeks to leave a meaningful mark on the world to help guide others who might feel lost.

The Psalmist acts as a church lector or choirmaster who reads from the wisdom verses of the Old Testament. He sings or recites traditional Christian psalms that advise congregation members to quietly endure life until they reach the afterlife. Unaware of the internal rebellion he sparks in his listener, he serves as the philosophical opponent to the poem's core message of active living.

The Shipwrecked Brother is a metaphorical figure representing individuals who become overwhelmed by the sudden troubles and sorrows of life. He wanders the shores of existence close to despair. He serves as the intended audience for the footprints left behind by great people, needing their legacy to take heart and keep going.
