The passionate shepherd offers all of his passion, pleasure and simple joys to his beloved except for 1 thing. And that is immortality. The passionate shepherd did not offered immortality to his beloved because his love to is romantic but unrealistic.
In the poem the passionate shepherd to his love by Christopher Marlowe, the shepherd offers love to his lover by expressing it in a different form by giving her joy, happiness, many gifts and so on. Shepherd does not offer immorality because it is far beyond for what is offering to his beloved. He proposes all goodness to her that nature can bring, which will make her content.
