I think you miss my point. You seem to be making an assumption that when I say 'experience' that man is his own arbiter of truth. The two do not necessarily cross paths. Were that what I was saying, your post would be appropos.
However, I will make one small point here. You said the following:
Those who would acquaint themselves with the things of God, and be assured of them, must know the Bible, for it is the summary of divine revelation.
This is an extrascriptural statement. You are basing this either on an extrascriptural assertion by another author, or on your own experience. Consider what Paul was writing to the church. He was writing based not on the written letter (though it was used at times to make an intellectual argument of some sort) but entirely on his experience with Christ:
But I certify you, brethren, that the gospel which was preached of me is not after man. For I neither received it of man, neither was I taught it, but by the revelation of Jesus Christ. Galatians 1:11,12
This, like grace, is no license to go our own way, but it is an exhortation (as Paul touches on in 2 Cor 3) to seek the Lord personally. It is simple to take an analogy of a friend. Supposing you had a friend that you knew intimately (your best friend, perhaps) and you wanted someone else to know him - the best way for anyone to get to know your friend would be meeting them in person. A book might give an overview, but one-on-one relationship is a MUST. Daily interaction is absolutely necessary.
Consider also, an historical figure (take Abraham Lincoln as an example). Now we have historians who are 'experts' in Honest Abe's life. Yet, like most biographers, they cannot fully agree with one another on everything. But we also have his contemporaries who wrote. This would definitely provide a reasonably good account of Abe's life - but since this is where our experts get their info, it is obviously not 100% perfect in reliability. Then, we have autobiographical information that Abe himself penned. Again, 'experts' have this info at their fingertips so, while these writings would be most reliable, they would be skewed by Abe's own biases. We might get some of his thoughts, but we still wouldn't really know the man. The letter CANNOT do what a relationship can do. Anyone who has EVER spent any amount of time emailing someone before they met that other person can attest to the limitations of writing - even as good writers as they may be. The spirit of a man cannot come across fully in writing, it can only come across in knowing the man personally. How much more with God? The letter, if it is insufficient to convey a man, it is infinitely more incapable of conveying God. It can ONLY be done through experience.
That is not to say the bible is wrong in any way. No. But to think that God is no longer the same, that He no longer hides things from the wise of this world and reveals them to the foolish of this world is not to be scriptural.
As an example of the secondary place of the scriptures to experience with God Himself, you should read a short bio of 'Holy Ann'. She was a simple woman - an Irish Immigrant to Canada in the late 1800's - who came to know the Lord personally. (I'm not sure about links on this site yet, so I'll refrain for now from posting it.)
Remember, Paul was entirely convinced that he had it all right when he was persecuting the Christians. He had the scriptures he commended to the churches. The same is true of Israel that saw Christ - they had the scriptures and most rejected Christ. Even the disciples were looking for the same thing the Pharisees looked for - a physical Kingdom. Unless something of spiritual truth is revealed by the Lord Himself, it will not be entirely real to the hearer - and thus not a thing of true faith. Merely intellectual assent.
And the Father himself, which hath sent me, hath borne witness of me. Ye have neither heard his voice at any time, nor seen his shape. And ye have not his word abiding in you: for whom he hath sent, him ye believe not. Search the scriptures; for in them ye think ye have eternal life: and they are they which testify of me. And ye will not come to me, that ye might have life. John 5:37-40
The Pharisees had the scriptures - just as we do and many say 'I believe it from cover to cover'. But the truth of the scriptures is not to be uncovered intellectually, but only experientially. Then the scriptures become life - unfolding truth to the seeker by the revelation of the Holy Spirit as one opens one's heart to Christ (Rev 3:15-22 tells us that and ends with this:
"He that hath an ear, let him hear what the Spirit saith unto the churches." Rev 3:22
