There are many ways in which to paraphrase this quotation. Let me give you a few variations.
You can say something like "In the messiness of diversity, we can find solace." Or you can say something like: "Paradoxically paradise is the ability to celebrate imperfections." Here is another paraphrase: "Paradise is not perfection, which does not exists, but the ability to embrace imperfection."
All of these paraphrases are variations on the original quote. As for how it applies to modern life, I would say that this quote is very important, because we do not live in a perfect world. In light of this, what we need to do is to make the best of things. When we do this, we will not achieve perfection, but we might find paradise. For instance, we might find forgiveness, reconciliation, understanding, and love.
