In Part VII of the poem, the mariner demonstrates his purpose in recounting his melancholy tale--he wants to warn the wedding guest of living a life in pursuit of selfish goals without care for other humans or elements of nature. As an older man struggling with his isolated existence, the sailor longs to keep others from choosing his turbulent path. He tells the wedding guest:
"He prayeth well, who loveth well/ Both man and bird and beast. / He prayeth best, who loveth best / All things both great and small; / For the dear God who loveth us, / He made and loveth all" (Part VII, Stanzas 22-23).
His words illustrate his belief that humans must not only have a respect and appreciation for God in order to have fulfilling human relationships but that they must also respect all living creatures in order to live in harmony with others.
