Well, you'll find it in the scriptures.
I Corinthians 2:6 We do, however, speak a message of wisdom among the mature, but not the wisdom of this age or of the rulers of this age, who are coming to nothing. 7 No, we declare God’s wisdom, a mystery that has been hidden and that God destined for our glory before time began. 8 None of the rulers of this age understood it, for if they had, they would not have crucified the Lord of glory. 9 However, as it is written:
“What no eye has seen,
what no ear has heard,
and what no human mind has conceived”—
the things God has prepared for those who love him—
10 these are the things God has revealed to us by his Spirit. (NIV) (Go ahead and read the entire chapter)
Even better, here's an account of a revelation:
Acts 22:6 “About noon as I came near Damascus, suddenly a bright light from heaven flashed around me. 7 I fell to the ground and heard a voice say to me, ‘Saul! Saul! Why do you persecute me?’
8 “‘Who are you, Lord?’ I asked.
“ ‘I am Jesus of Nazareth, whom you are persecuting,’ he replied. 9 My companions saw the light, but they did not understand the voice of him who was speaking to me.
10 “‘What shall I do, Lord?’ I asked.
“ ‘Get up,’ the Lord said, ‘and go into Damascus. There you will be told all that you have been assigned to do.’ 11 My companions led me by the hand into Damascus, because the brilliance of the light had blinded me. (NIV)
Really now? You can study and still not possess it.
John 5:39 You study the Scriptures diligently because you think that in them you have eternal life. These are the very Scriptures that testify about me, 40 yet you refuse to come to me to have life. (NIV)
They call him Lord, Lord and even prophecy in his name... they just don't feed his brothers and sisters. They sought after knowledge and not love.
There's a lot in that short passage. What part don't you understand? I'll leave you with this final passage, but you should study the roll of the Spirit in how we learn about God...
II Corinthians 3:17 Now the Lord is the Spirit, and where the Spirit of the Lord is, there is freedom. 18 And we all, who with unveiled faces contemplate the Lord’s glory, are being transformed into his image with ever-increasing glory, which comes from the Lord, who is the Spirit. (NIV)
