@Jonaitis First I want to say I don't fault you in the least for all that you have posted, I have found we each have our different ways of coming to know Him who saved us, and expressing that to others. I see you as a sincere, perhaps brilliant young man, that just truly wants to have the best representation of Christ possible because you love Him so, and for that I commend you.
With that said, in my own case, I needed no other knowledge some 30 years ago, reading Romans 8,crying out tears of repentant and forgiven joy, than the undeniable, profound witness and event that had just happened and was continuing to happen to me in my bedroom. The God of this universe knew who I was, Knew where I lived, And had just come into my heart and in my room. The whole room literally took aglow, time seemed to stop, the world seemed to stop and everything came so divinely and serenely still. I couldn't have told you one thing about the chronology of the Bible, and probably couldn't have named the 4 gospels to you if you had spotted me Matthew and Mark. But at that moment there was no doubt I knew that the Jesus Christ of Nazareth spoken about in the Bible was true, And I had just met Him in my room. All the scholars in the world could have come and tried to convince me otherwise, but with tears of inexplicable joy I would have just shook my head and said, " It matters not what you say, I know, I know Him, He is real, He is real, He has just come to visit and save a broken sinner like me. He is right here in this very room."
It therefore warmed my heart some years later when I read an Oswald Chambers devotional of something very similar. He said and I quote
It is possible to know all about doctrine and still not know Jesus. A person's soul is in grave danger when the knowledge of doctrine surpasses Jesus, avoiding intimate touch with Him. Why was Mary weeping at the tomb(John 20:11-18)? Doctrine meant no more to her than the grass under her feet. In fact any Pharisee could have made a fool of Mary doctrinally, but one thing they could never ridicule was the fact that Jesus had cast out seven demons from her; yet his blessings were nothing compared to knowing Jesus Himself. Mary knew Him. ... Jesus said to her, "Mary!" Once He called her by name, she immediately knew that she had a personal history with the One who spoke, " She turned to and said to Him, Rabboni!" {End Quote}
And that is the way I have found the knowledge of Him to be ever since that night in my room. I come to know more and more of Jesus and His ways through pain and sorrow, suffering and the cross, through difficulty and experience, through the backside of Midian and being brought to realize what it means to lose my life in this earth for the sake of Knowing Him, than I ever would through all the reading in the world. It has been like that for me. It is like that for others I believe.
His word then is brought to light through my experiences rather than reading things about Him bringing me to experiences in knowing Him. If I had never been brought through something, I don't know if He could have ever shown me something. The disciples hearts on the road to Emmaus were opened to the revelation of the scriptures by the Lord through something they had just been taken through; though it had been right there before their eyes the whole time. It took the experience to see.
One other thing before I go. God makes no apologies for Himself and neither should we. He is who He is and His word is what it is. He lets it be what it is. What are we and the world going to do with that? He is not looking for you to help Him out, to solve these mysteries, though I know you love Him so. Perhaps the best we can do is pray for others, pray He will pull beside them just as He did on the road to Emmaus and opened their heats. Pray He will make Himself known. And once He does that All the doctrine and chronology in the world will mean nothing anyway. We will know Him as He desires to be known.
