The mathematician Georg Cantor wrote in his 1867 doctoral thesis, “In mathematics the art of asking questions is more valuable than solving problems.” Not just in mathematics! Asking questions about God is essential for our spiritual growth. Of course we must decide about the foundational ideas of sound doctrine along the way; but as far as our steadily growing in faith is concerned, it is healthy to keep restocking our mind’s shelf with new sets of unanswered questions. After all, “Faith is the substance …of things unseen” (Hebrews 11:1). So to be growing in it is to have unanswered questions.
I expect that the hunt will continue in heaven. Just because we will be there does not mean we will have shrunk the incomprehensible complexity of God to fit into our new minds, thus diminishing God to something other than he is — the incomprehensible God — by definition. Galileo wrote, “There are such profound secrets and such lofty conceptions that the night labors and the researches of hundreds and yet hundreds of the keenest minds, in investigations extending over thousands of years would not penetrate them, and the delight of the searching and finding endures forever.”
I discovered these wonderful quotes by Canton and Galileo in an article about infinity on https://wng.org by Matthew Connally, Professor in the Department of History at Columbia University in New York (https://wng.org/roundups/materialism-101-what-is-infinity-1628946910).
