Although we cannot define God, we can describe God. Our descriptions of God will be proportional to what God desires us to know. Yet being finite, there are of course limits to what we can know of God. With respect to mode or manner, God cannot have us know him as he knows himself. We’d have to share the divine essence to know God originally or intuitively. We can apprehend God, but we can never comprehend God. To comprehend God is to know God exhaustively, as God knows God.
We know God partially and imperfectly, yet we can know God sufficiently. Although we do not know God univocally, as there is no identity between God’s self-knowledge and our knowledge of the Divine, we are not left to equivocal knowledge either. There is true correspondence at the point of the analogical. Notwithstanding, the perfect revelation of God is revelation of the original. God’s revelatory self-disclosure is an accommodation to created beings. The reality behind the revelation is greater. God’s revelation of himself is not himself. God transcends his revelation.
Although God is incomprehensible, God is not “wholly hidden.” What should humble us should not lead us to despair. Although God’s thoughts are not our thoughts, and our thoughts can never attain to the heights of God’s thoughts, the things God has revealed belong to us and to our children forever. (Isaiah 55:8,9; Deuteronomy 29:29)
God is knowable. If nothing else, we know God is incomprehensible(!), but by grace and pure condescension we know much more. For God has spoken to us in Christ, who is the radiance of the glory of God and the exact imprint of his nature. (Heb. 1:2,3)
Jesus said to him, “Have I been with you so long, and you still do not know me, Philip? Whoever has seen me has seen the Father.”John 14:9
