The speaker closes the poem by expressing that she and her spouse should love each other so much that they will live eternally while they are still living. They will "live eternally" in this manner. But she might also be implying that immortality—a life in heaven—depends on how much one loves while living. If you love enough, you will be able to live forever with God. This interpretation comes from the fact that she says that they will live "eternally" even though they are still alive today. Some scholars believe that the word "eternally" here means for all time rather than for always. If this is true, then the couple in the poem could die someday after all. Immortality has been a popular topic in poetry for many years. This poem is just one of many about people who have sought to extend their lives through science or religion.
