But as it is written, Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him. But God hath revealed them unto us by his Spirit: for the Spirit searcheth all things, yea, the deep things of God. For what man knoweth the things of a man, save the spirit of man which is in him? even so the things of God knoweth no man, but the Spirit of God. Now we have received, not the spirit of the world, but the spirit which is of God; that we might know the things that are freely given to us of God. ~ 1 Corinthians 2: 9-12
The soul leaves all surface appearances, not only those that can be grasped by the senses but also those which the mind itself seems to see, and it keeps going deeper until by the operation of the spirit it penetrates the invisible and incomprehensible, and it is there that it sees God. The true vision and the true knowledge of what we seek consists precisely in not seeing, in an awareness that our goal transcends all knowledge… ~ St. Gregory of Nyssa
