“Call to me, and I will answer you, and I will tell you great and mighty things which you do not know” (Jeremiah 33:3).
God knows a zillion things we do not.
Let’s start with that no-brainer.
The overwhelming majority of “things God knows” are, I expect, reserved exclusively for Him. “The secret things belong to God,” we’re told in Deuteronomy 29:29. The farthest reaches of this enormous universe are seen and appreciated only by Him and His legions. And the heavenly realm itself is His and His alone.
However.
The Heavenly Father has many things He is dying to show us, to reveal to us, to allow us to stumble upon, or learn in His classroom.
