This is paraphrased in "Karl Barth's Conception of God" (1952) http://mlk-kpp01.stanford.edu/primarydocuments/Vol2/520102BarthsConceptionOfGod.pdf by Martin Luther King, Jr.: God is the one who stands above our highest and deepest feelings, strivings and intuitions.
Dogmatics in Outline (1949)
Context: He is the One who stands above us and also above our highest and deepest feelings, strivings, intuitions, above the products, even the most sublime, of the human spirit. God in the highest means first of all … He who is in no way established in us, in no way corresponds to a human disposition and possibility, but who is in every sense established simply in Himself and is real in that way; and who is manifest and made manifest to us men, not because of our seeking and finding, feeling and thinking, but again and again, only through Himself. It is this God in the highest who has turned as such to man, given Himself to man, made Himself knowable to him … God in the highest, in the sense of the Christian Confession, means He who from on high has condescended to us, has come to us, has become ours.<!-- p. 37
