We can only know those things of God that he chooses to reveal. Even as we read the word of God it is only words on a page and intellectual concepts until the Spirit of God bring life and light to these words and they become reality to us. No man can know God unless God chooses to reveal himself.
Every revelation given to every person, every profound book and teaching in reality a gift of God. God wants us to know Him this is why he wrote the book this is why he sent His Son Jesus. But the reality is no preacher or teacher or prophet, any man or women of God must always remember it is God's grace to reveal himself to any of us.
No man can know God unless God reveals himself, yet the Creator and author of life is knowable and visible in all his creation. If any person really wants to know and understand and asks, God will reveal His truth to you.
As a younger man I journeyed through eastern mysticism, studying the teachings of a powerful and famous guru. I dabbled in witch craft and "mind control" with amazing results, then moved to study Mormonism and other "Christian " religions. After not finding any comfort or peace in any of these I began to just talk to God...... "I know you are out there, I know there must be more to life than just a short 70 - 80 years and then become fill for a hole in the ground. What is the story? What is the real deal?. "
On a quiet Saturday morning at our home in Danbury Connecticut as I lay on my bed half resting, half meditating on theses questions my room went blinding bright white. In the midst of this Glory Stood Jesus. He did not speak a word, but I instantly knew: He is God, the Son of God, He died on the cross to pay my penalty for all my sin, I had a decision to make to receive Him and what he has done for me or reject Him and his substitutionary work. As I lay there unable to move I was overwhelmed, flooded and saturated with a level of love indescribable. I could only lay there and weep. As I said yes Lord, an amazing power again indescribable, overwhelmed me, it pierced through the top of my head and flowed out the bottom of my feet. As this power flowed through me it washed me clean, I felt all sin, all condensation, guilt, regret, fear flow out the bottom of my feet.
I did not understand much, but this I knew and still know regardless of anything else happening, when I leave this world I will spend eternity where ever He is.
When I was finally able to get up and walk out of that room I thought I was the first person to meet Jesus in 2000 years. Since then, of course, I have learned that many know him, many follow him, many talk with him and he talks with many. In that super natural moment he deposited certain truths into my heart first being he is who he said he is and the Bible is the inerrant unchanging word and will of God for all men. It is the supreme truth in this world.
Some time after that life changing day I asked the Lord, "how is it, I pursued many false and deceiving paths, yet in the end I was not held by them but ultimately came to Him, or more accurately he came to me? This is how the Lord explained it to me.... He said, "throughout that search, you were not looking for self aggrandizement, enlightenment, power, or wealth, your search was for truth ...... As long as anyone sincerely searches for truth it can ONLY lead to one place...it leads to me."
in John 14:6 Jesus said to him, "I am the way, and the truth, and the life. No one comes to the Father except through me.
Do not take any mans word for it, ask God to reveal His truth to you and He will.
