Moreover, the speaker returns to the present and says that he would not write anything if he could only know the miracle she was. By this, he might mean that sex with her would be such a miracle that it would no longer be describable in words, as their spiritual connection would be embodied physically. He could also be saying that he would throw away their spiritual virginity if could on have sex, and there would be no need for language.
Furthermore, the purpose of the majority of the poem, with respect to the exploration of the speaker's grave being dug up, is to make a conceit glorifying how vast the spiritual love of the speaker is. Generally, grave digging is not something associated with love. Yet, the speaker says that when they are dug up, the digger will "thinke that there a loving couple lies." This might mean that something will compel the person digging the grave to believe that they were a loving couple. The love in their relationship is so strong and obvious that it can even be seen when they are dead. Moreover, as re-dug, the two will be adored and people will see the miracle of their sacred love. Donne manages to make the grave digging seem like a glorious occasion as he compares it to love. Also, like the afterlife, their love becomes eternal.
Along with that, there is religious imagery and allusion associated with the speakers love as shown through the digging. An example of this is in the conclusion of the first stanza. By "busie day" Donne might be referring to judgment day; this communicates holy love as souls are staying together on the final day. Next, the speaker says that he and his lover will become reliques. They are in this case holy as evidenced by the mention of Mary Magdalen. In this case, the speaker is probably saying that people will view his relationship with his love as they do Jesus and Mary. Both pairs had an extreme spiritual connection, but never made love.
