Alongside all our knowing must be the equal and remaining “knowing that I do not know.” That’s why the classic schools of prayer spoke of both kataphatic knowing—through images and words—and apophatic knowing—through silence, symbols, and beyond words. page 
Richard Rohr : "Strangely enough, this unknowing is a new kind of understanding. We do have a word for it: the old word faith. Faith is a kind of knowing that doesn’t need to know for certain and yet doesn’t dismiss knowledge either. With faith, we don’t need to obtain or hold all knowledge because we know that we are being held inside a Much Larger Frame and Perspective. As Paul puts it, “For now we see in a mirror dimly, but then we shall see face to face. Now I know only in part; then I will know fully, just as I have been fully known myself” (1 Corinthians 13:12). **It is a knowing by participation with—instead of an observation of from a position of separation. It is knowing subject to subject instead of subject to object."** (emphasis added)
