Isaac of Nineveh

From what Isaac has to say, I think that the first passage is the only one that stuck out to me. What made me curious is how he mentions an infinite type of love. This sparked my attention because I feel like he is comparing the love of god lasting for eternity to the love of a spouse. I could be wrong but I feel he did this comparison to show just how strong God's love is especially when it is contrasted against the next biggest love. This is profound because if he is indeed comparing these two things, is it to justify his place as God or is it for us to feel--for lack of a better term--human?
