You should put your faith in God/Jesus - always.
A part of this is to follow His admonition to "be sober" - meaning - to not let the worldly 'cocktail' get you "drunk" and rob you of your spiritual discernment of things in the world.
God speaks to us by/through/with His Holy Spirit; however, His 'word' for us is a message given in the form of an inspired written record of the things He wants us to know. Until His Second Coming, Jesus does not come to us personally (bodily) to tell us things; rather, it comes to us from His 'word' and the Holy Spirit. And, it is not that He could not do it differently if He chose - it is the way He chose.
What happens if the 'word' that He intends to teach you how to have spiritual discernment becomes corrupted?
How will you learn how to have enough spiritual discernment to recognize and realize that it has been corrupted?
A part of spiritual discernment is having the spiritual discernment to recognize and realize when
it has been corrupted.
A person who has grown up studying the KJV is able to 'see' - "in spades" - the corruption that exists in the modern bibles.
Moses is just a brother who cares enough to try to warn you that you should be careful not to let the corrupted worldly cocktail rob you of good solid spiritual discernment - which will be corrupted if you attempt to obtain it from a corrupted bible.
It is not about putting your faith in Moses; rather, it is about "being sober" [enough] to discern the information you are given.
We all have to discern whatever we are given - whatever we are told - whatever we experience - etc.
We even have to discern whether or not the source of information is a good source of information.
Yes - it is complex.
Nonetheless, we have to do it.
What ultimately matters is - what you do with the information.
If the mere mention of the KJV agitates you, makes you angry, etc. - this is a CLUE!
That is just the devil (or a demon) standing next to you with a "cattle prod" - poking you with it in order to provoke you so that you might 'dismiss' the KJV. That is just how badly the devil does not want you to pay any attention to the KJV.
It happens all the time... (The mere mention of the KJV seems to instantly make certain members of CC absolutely livid!)
Corrupted bibles will have you drinking the worldly cocktail without recognizing it or realizing it - robbing you of good solid spiritual discernment.
So - pray about it - ask the Lord to help you discern the truth...
