"Through wisdom is an house builded; and by understanding it is established: And by knowledge shall the chambers be filled with all precious and pleasant riches." (Proverbs 24:3-4)
"Therefore we ought to give the more earnest heed to the things which we have heard, lest at any time we should let them slip." (Hebrews 2:1)
Aphasia is the neurophysiological term for loss of speaking ability (there are many types). It's absolutely disconcerting if you've ever seen it firsthand. I wouldn't recommend it. The individual in question knows something's missing but can't quite put their finger on it. At a deep level, you might be able to understand by intuition what they're trying to say but that's only because you know them. As I did the individual in whom I watched this take place. Scary. It was an acute instance brought about by a blood infection and they recovered, thank God, but it's something I wouldn't ever want to go through or witness again.
"My zeal hath consumed me, because mine enemies have forgotten thy words." (Psalm 119:139, emphasis mine)
It would seem the same has happened in many ways to modern, mainstream Christianity. And I don't mean to be disrespectful. The word of God, the Bible, while it may be the most-read book in the history of the world, is also an eminently word-of-mouth book. An oral tradition, even.
"And these words, which I command thee this day, shall be in thine heart: And thou shalt teach them diligently unto thy children, and shalt talk of them when thou sittest in thine house, and when thou walkest by the way, and when thou liest down, and when thou risest up." (Deuteronomy 6:6-7)
That's what my dad did for me. Growing up, I'd struggle through the Proverbs and--like a scaffolding--what verses I could understand at the time would set up their skeletal frame around my burgeoning mind. The necessary understanding of the finer points of Solomon's writings filled in over time--they continue to do so. Point is, I never forgot the words. They're ingrained. But just because I can recall chapter and verse, doesn't mean that I'm living it without knowing Jesus. The Living Word. As all language has sprung from the same source, a "language singularity" as it were, the whole of the Bible is meant to flow into knowing Jesus. And, as I've said before, when a Christian doesn't know Jesus, it's the worst kind of paradox.
"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 5:39-40) This is Jesus talking to the Pharisees.
The King James Bible has affected and infiltrated Western culture more than any tome in history. Gutenberg's Bible may or may not have been the first book ever printed with movable type (there has been skepticism recently). As ubiquitous as the Bible has been in the past thousand years, the power inherent--the power of the Holy Spirit--has not been seen in a commensurate display (in my opinion). And why is this?
"Am I therefore become your enemy, because I tell you the truth?" (Galatians 4:16)
All I can say is, treat Jesus as if He's a real person. Like He's your best friend. It's true. And if we act on the truth of God's word, whether we know all the words, or not, He will build up that which we're lacking, and our faith will strengthen over time.
"But what saith it? The word is nigh thee, even in thy mouth, and in thy heart: that is, the word of faith, which we preach;" (Romans 10:8)
