I have to preface my comment by saying, "I am not a wise man." Nothing I say is the last word on anything. And I can only speak from my own personal experience.
During my years as a hermit, I only had the internet to keep me busy. (I haven't even owned a TV in 15 years.) In that time, I would watch more sermons and YouTube videos in a week than any pastor could preach in a year. I'm not exaggerating. Because of this, I became personally and closely familiar with every craze, phase, revelation, mystery, secret society, sign, wonder, miracle, theory, plot, prophecy, puzzle, dream, vision, and word from the Lord that's been proclaimed. You name it, I probably know it. If I were to describe the extent of it, your head would explode from the sheer volume of information. If I told you about how bombarding myself with years (italics, bold and underline "years") of this stuff affected me, it would make your heart hurt. It was a living hell.
Bible codes? I'm familiar with them and the people who research and study them; from Rabbi's to YouTubers, whether they be nut jobs, deceivers or sincere seekers of the Truth.
Bible codes are something that I believe people need to speak about with caution and discernment, but also with respect and the fear of the Lord. This is God's actual words that are being handled. That's never to be done lightly or casually. Anyone treating Bible Codes like a Ouija board to predict the future is treading on thin ice and playing with fire... at the same time. And we all know fire and ice don't mix.
But, to dismiss the Bible codes as fake or a complete deception, and doing THAT casually or flippantly, is equally as unwise.
That said, the Bible is very complex, and very simple, at the same time. Is it possible that God hid messages in His Word to be discovered during these last days? Absolutely. There were prophecies that people couldn't understand for centuries that today, we DO understand. At the same time, God wants us to understand His Word. I'm of the belief that simply reading the scriptures is all we need. And I don't see any hints, or examples, of Bible codes being used in the teachings in the scriptures.
Like many things, there's a great danger of getting caught up in Bible codes. I've seen many people on YouTube change their doctrinal beliefs based on what they (or someone they follow on YouTube) profess to have found in the Bible codes. I have seen people go from seemingly normal to outright weird and wacky.
Then there's the fact that Bible code methods and interpretations depend widely upon each code searchers bias, understanding, and perspective. I've seen one code searcher take another code searcher's table and interpret it in a completely different way, often adding, subtracting or "correcting" what the other had. Part of discernment is learning who the code searcher himself is... but multitudes don't even think about that. The enemy is drastically underestimated when it comes to his abilities to deceive. If the Bible codes ARE real, then WHICH code searcher is to be believed with all the variances out there?
Not to mention that there are too many code searchers who haven't given a thought about how their research and interpretations are going to affect those who listen to them. I've seen subscribers on YouTube get pretty messed up by this. It's not pretty.
I just don't think the Bible codes are something to be dabbled in, especially out of curiosity. I believe it's entirely possible that God COULD HAVE created Bible codes. But, I don't see the need for them because there are many scriptures that say the scriptures themselves are enough. If someone is going to research Bible codes, it should be done ONLY after prayer, fasting and seeking the Lord to ask if it's HIS will for you to do so. Examine your motives. Ask yourself what it is you're wanting to accomplish by doing this because it doesn't come without responsibility.
Like I said, real or not, they're the very words of God that are being handled. And that's never to be done casually or lightly. And from my personal experience, I myself found it best to not get involved. If God wants me to know about a particular Bible code, then I trust that He's a big enough God to make sure I hear about it and confirms it in my spirit.
