I believe the King James Bible to be the inerrant perfect Word of God that is faithful translation from the original languages. For I believe it is divinely inspired preserved Word. It is not improvement upon the originals, nor is it inferior to them. Now, while I may believe the KJV is perfect and without error, from my experience, I have found that most KJV-Onlyists believe that you should only read the King James. Many will also say that the King James is not all that hard to understand, too.
I disagree with both of these conclusions. So while I believe the KJV is the divinely inspired Word of God, I do not think one should stick to just reading it alone. For I have found Modern Translations to be very helpful in updating the language (From Old English); However, I do not put my entire trust in Modern Translations because the devil has placed his name all over them and key doctrines have been watered down and important messages within God's Word have been neutered.
In other words, I read Modern Translations as if I am panning for gold. I have to sift thru the dirt or the garbage in order to get to the gold of the passage that lines up with the King James.
This gold that is found within the dirt of the translations can be very useful because it reflects what is in the King James. This is the gold that people hear and are saved when they hear the gospel message. For someone can be saved just by hearing a few Bible verses about the gospel message of Jesus Christ. This gold shines thru and penetrates their heart.
Like the Parable of the Sower. Believers receive the Word of God into their heart from those passages that are talking about salvation. Words that line up with the King James. These words are sown in their heart. And if they let this Word take root in their heart by continually reading the Word of God, then they will have hidden His Word in their heart so they will not sin against Him. It will have taken root and they will not fall away due to persecution or the trials of this life.
For it only takes a few Bible verses to get someone saved. However, washing yourself with the water of the Word is going to be a lot more effective if you use the pure Word of God. For we received the Word not as the words of men, but as the very words of God (1 Thessalonians 12:3 KJV). For if one second, I could not trust even just one word of God, then what makes you think that I could not trust the rest of the words within His Holy written Word? No, I did not receive the Word of God as the words of men but as the very words of God (just as Thessalonians states).
However, that said, I believe God had inspired His Word in the King James for three major reasons based on Scripture.
Three Scriptural Reasons to Trust in A Perfect Word Today.
#1. God's Word claims that it is perfect
God's Word claims that it is perfect (Psalm 12:6 KJV) (Psalm 119:140 KJV) (Proverbs 30:5 KJV) and that it will be preserved for all generations (Psalm 12:7 KJV) and it will stand forever (Isaiah 40:8 KJV) (1 Peter 1:25 KJV). Therefore, seeing Scripture plainly states these facts, it then becomes an issue of a test of your faith in God's Word (See the test the devil gave to Eve in Genesis 3:1 KJV); Because, when ye received the word of God which ye heard of us, ye received it not as the word of men, but as it is in truth, the word of God, which effectually worketh also in you that believe (1 Thessalonians 2:13 KJV). In other words, do you believe you hold the very words of God within your hands like the disciples did?
#2. KJV vs. Modern Translations
A simple side by side comparison of the KJV vs Modern Translations shows us that the devil tries to place his name in the Modern Versions. Have no idea what I am talking about?
Well, many Bible versions say that it is the dragon who is standing on the sea shore in Revelation. This is just evil and wrong.
See Parallel Version for Revelation 13:1 here...
Revelation 13:1 The dragon stood on the shore of the sea. And I saw a beast coming out of the sea. It had ten horns and seven heads, with ten crowns on its horns, and on each head a blasphemous name.
See, if you know anything about Bible language, standing on something means that you "own it"; And the devil wants to own you. In the King James, John is standing on the seashore. Yet in many Bible versions the dragon (i.e. the devil) is standing on the seashore.
Why is this a problem?
Lets look at...
Genesis 22:17"That in blessing I will bless thee, and in multiplying I will multiply thy seed as the stars of the heaven, and as the sand which is upon the sea shore; and thy seed shall possess the gate of his enemies"
Did you catch that? God says to Abraham that He will multiply his seed as the stars of the heaven and as the sand which is upon the seashore where he will then possess the gate of his enemies (i.e. the devil and his kingdom). The apostle John who wrote Revelation was Jewish and he was the promised seed of Genesis 22 standing on the seashore in Revelation 13. It was not the dragon or the devil standing on the seashore.
For certain Modern Versions eliminate the part of the passage in Revelation 13:1 that says that John is standing on the seashore (When he refers to himself as "I").
Also, the devil tries to take out key points in important discussions within the Bible (Which can effect doctrine). For example: In Romans 7 Paul talks from the Jew's perspective in keeping the Old Testament Law (Which leads to problems), and he gives us the climax or heart of his message as a solution in Romans 8:1 KJV. Now, certain modern translations have eliminated "who walk not after the flesh, but after the Spirit." Eliminating this passage destroys the whole thrust of Paul's argument. Walking in the Spirit is the key to being in Christ Jesus. You eliminate that and you destroy Paul's argument. Also, 1 John 5:7 KJV is the only verse in the Bible that is the clearest and most concise teaching on the Godhead (i.e. the Trinity).
#3. Biblical Numerics
Bible Numbers that glorify God and His Word. (Note: These are not equidistant letter sequences or numbers that attempt to get one to have a special dream, or to divine the future in some way - Striving to foretell the future is forbidden in the Bible). Numbers are something that we deal with in our every day life and all things glorify God. So obviously the numbers in God's Word would naturally glorify Him in some way. What am I talking about? Check out this video on Numbers & the Greek New Testament.
Also, here is a recent post of mine on the topic of Bible Numbers.

In fact, here is a great study on Bible Numbers based off of the King James.

Also, here is a video series by Mike Hoggard that talks about the number 7 in the King James.
Now, while I may not agree with Mike on everything he teaches in the Bible nor on the way he teaches Bible numbers in every example, I have found that he has made some startling discoveries. Discoveries that do not appear in the modern translations but only in the King James.
Important Note:
Also, I want to add that sometimes these numbers match up with Blue Letter Bible and other times they do not. This is because BLB uses a different version of the KJV I believe. If you download Mike Hoggard's free software search program from his website, you can verify the numbers (in his study) with his program here...

Oh, and Mike does not make an error in one of his calculations in the first video and I do believe he mentions his mistake in a later subsequent video.
I hope this helps.
And may God bless you all.
