Our "knowledge" of God is merely recognizing how much we don't know about God. Honestly, knowing God as He is, not as He is mediated to us by Jesus, is un-knowable, since He is transcendant and beyond our ability to know Him. Our minds cannot handle the concept of "infinity" or "eternity". Accepting this lack of knowledge is indeed human wisdom.

Does a “renewed mind” know more of God than a mind that has not been so renewed?
