I expect that you, like me, have many questions about the "deep things of God." We have questions that we really want the answers to. Questions about doctrine; questions about suffering; questions about the angels, the fall, predestination, evil, the cross... and many more besides. And there are many questions to which we don't know the answers; and the Bible doesn't seem to give us an answer.
Hmmm... Then we have to trust. Which is not a bad thing.
I am comforted by the fact that one of the greatest Theologians who has even lived, John Calvin, said time and again that there are things we do not know about God, and questions that cannot be answered about His ways and plan. And even… that we should not pry into these things! I'm trying to read through Calvin's Institutes in a year (I found a plan on Google - which does seem to have millions of answers), and as I do so I jot down the times he says that he does not know about certain things concerning God and His ways. Take a look at these quotes:
"In all religious doctrine, we ought to hold to one rule of modesty and sobriety... Not to speak, or guess, or even to seek to know, concerning obscure matters anything except what has been imparted to us by God's word" I.xiv.4
"Let us use great caution that neither our thoughts nor our speech go beyond the limits to which the Word of God extends." I.xiii.21
"It is not worthwhile anxiously to investigate what does not much concern us to know." I.xiv.7
"I dare not affirm with confidence..." I.xiv.7
"I do not know..." I.xiv.7
"I prefer to leave that an open question." I.xiv.8
"Among those mysteries whose full revelation is delayed until the last day... Therefore let us remember not to probe too curiously or talk too confidently." I.xiv.8
"But the reason... lies hidden in his plan." I.xv.8
We must not "manifest an inordinate curiosity." II.ii.10
Another Theologian I enjoy reading (but very carefully and discerningly as he had some, to my mind, not-so-good-views of God's Word and things) is Helmut Thielicke. He also reckons there are certain things we do not know because God has not revealed them to us.
"I believe that even pious ideas are forbidden if their purpose is to fill out gaps which God has obviously left open."
"...stop trying to give a 'solution' of the problem and rather point the way to a 'deliverance' from the question itself."
"So there are no answers to many questions that faith asks, at any rate no answers that can be given in the style of dogmatic statement."
And so I content myself with trusting where I do not understand; of believing though I cannot see; and of parking my faith at the fence of the mystery, waiting to one day go inside and see all. (1 Cor 13v12)
And of shouting loud in a terrace-chant kind of way, with the second greatest theologian ever, the Apostle Paul: "Oh, the depth of the riches of the wisdom and knowledge of God! How unsearchable his judgements, and his paths beyond tracing out. Who has known the mind of the Lord? Or who has been his counsellor? Who has ever given to God, that God should repay them? For from him and through him and for him are all things. To him be the glory forever! Amen." (Romans 11v33-36)
And then singing
"I am not skilled to understand
What God hath willed, what God hath planned;
I only know at His right hand
Stands One who is my Saviour."
