That speaks volumes!
You and I can not discover the truths of heaven through our own abilities. No amount of study, research, education, reasoning can reveal heaven. Understanding and wisdom are granted, not built. These things are of God, not man.
Remember that tree back in the garden? The “knowledge of good and evil”, that talk about “become like God”? Are we still tempted today as Adam was? Did we not learn anything from the fall of man?
Seeking to know the things of God through our own efforts, is both pointless and dangerous. That IS what Adam did! That is why sin and death and suffering entered the world! Are we to rise above sin through yet more of man’s effort?
“Granted”. That requires desire, asking, and receiving. We seek wisdom from the source of wisdom, not from our own efforts to become wise like a god! We must be humble enough to simply ask. He will not deny understanding to those that ask, but wisdom is not granted to those who seek to build it themselves.
What then? Is study bad? Is research evil? No! This is about the order of things, not the things themselves. First we seek to be granted wisdom, to see, to hear. We seek because we accept that is must be granted, not built. Then we study out of faith that the Holy Spirit will grant understanding. We study scripture not to gain understanding, but because we have been granted understanding and wish to use it!
If scripture seems flat, dead, shallow, then pray for understanding. No amount of reading or study will bring it alive, only God can grant it. Seek Him! Ask Him! It comes not through our efforts, but by His grace.
Don’t be like the Israelis who shook with fear at the foot of God’s mountain and told Moses “you go talk to Him and tell us what He says”. How sad! God wants to speak to you! Directly! He desires to grant YOU the wisdom of heaven.
All you must do is ask.
