I expect the poem to be about future, because the world “morrow” refers to  tomorrow.

 The poem is arranged into three stanzas, of seven lines each and the song has a regular pattern. The song start with the question. The song is reflective, it makes the speaking voice reflect on the good morrow. In the first stanza the speaking voice asks three rhetorical questions, which refers tho the lovers, did they lived before they knew each other? Therefore, the first stanza is a declaration of love that the poet makes to his beloved, asking himself three rhetorical questions and afferming that life they lived before knowing each other was empty and without any sense.

In the second stanza it is early morning, the two lovers are together.

In the following lines, the speaker is proving that any temptation outside is worthless. His eyes are controlled by love, therefore everything he sees is transformed by his adoration.
