Knowledge is grounded even as it is given by Him who gives it. Knowledge is a function of the soul rather than the massive collection of theories and facts produced by the scientific method. Grounded and given by God, linked with language through revelation, knowledge is far more concentrated than the contemporary world takes it to be. Those who are deaf to this knowledge are wandering in a landscape of dreams. This is because of the heresy of Gnosticism.
Revelation is never complete.
History was broken with the coming of Christ. Our lives, to the extent that we follow Christ, must continue to fulfil some small part of this realization. To realize here is first to know, and then to make actual our part of knowledge in the fallen world. Our knowledge and faith is made actual both through our own creative works and through what we let wither away as being of the outside, as being inessential to the Work we recognize. The question of the Fall.
