Proverbs 25:2
These also are proverbs of Solomon which the men of Hezekiah king of Judah copied: It is the glory of God to conceal a matter, But the glory of kings is to search out a matter.
Deuteronomy 29:29
“The secret things belong to the LORD our God, but those things which are revealed belong to us and to our children forever, that we may do all the words of this law.
There is a principle that I want to extract from these two verse of Scripture, that is the truth that God does not reveal to us all that there is to know about a given subject. He only gives us what He deems is most expedient (i.e. useful, helpful, needful, etc.). The Bible is not an all-inclusive revelation about all there is to know about all there is to know (I think I just confused myself).
Romans 16:25
Now to Him who is able to establish you according to my gospel and the preaching of Jesus Christ, according to the revelation of the mystery kept secret since the world began
1 Corinthians 2:7
But we speak the wisdom of God in a mystery, the hidden wisdom which God ordained before the ages for our glory,
God has chosen to keep some things (i.e. revelation knowledge) hidden from us. God by His Word calls them mysteries We know only those mysteries that the Word has already revealed to us.
1 Corinthians 13:12
For now we see in a mirror, dimly, but then [when we get to Heaven and see Jesus] face to face. Now I know in part, but then I shall know just as I also am known.
We will know even as we are known once we (those of us who are saved) get to Heaven. Again, you are all invited to come to Heaven. But you must come through Jesus to get there.
