"The Seafarer" presents two somewhat contradictory conceptions of God. On the one hand, God is similar to the Anglo-Saxon idea of fate – a vaguely ominous force that determines the outcome of events in a person's life, and before whom all human beings are basically helpless. On the other hand, God is the creator of the "firm foundations" on which the world stands, and the solution to our seafarer's restlessness. God is the only truly lasting thing available to mankind, trumping gold, glory, and other earthly pleasures. So, our speaker suggests, we should stop worrying about what God-fate has in store for us, and instead to focus on getting to our true home in heaven. This conclusion poses an interesting interpretation of the poem. Could it be that all of the seafaring in the poem may be an extended metaphor for the spiritual journey of the Christian soul? Changes things up a bit, huh?
No doubt about it: all of the travel in "The Seafarer" is really an extended metaphor of the spiritual journey of the Christian soul.
"The Seafarer" presents God as the ultimate source of stability and stillness, the antidote (cure) to the restlessness of the speaker's soul.
