Wonder arises in the mind when, what started to be a problem, turns out to be a mystery.
In a problem there is nothing to be known besides a solution, but in a mystery there is no final solution, but a continual growth towards contemplation. You face a problem but you plunge into a mystery. When a problem is once solved, you do not want to think about it any longer, but the more you think about a mystery, the more you want to think about it. Mysteries are undeciphered messages from our eternal lover and the supreme object of our love. Father Leonard Feeney said once that mysteries are not things about which we can know nothing but things about which we cannot know everything, precisely because there is so much to be known.
