The main problem is the etymology, the original writings are in Hebrew, Aramaic and Koine Greek. In the discipline of interpretation (exegesis) and translation of the bible, its important to stay as close to the first generation of a translation.
The 1611 King James Bible is an accurate translation from the original languages to English. In order to read a more complete translation words that were added to the bible for continuity are in italics. If you read an account without the italics you will get a more direct translation of the text.
Why does etymology matter? In the Hebrew or Old Testament God uses the word “meek” to describe Moses.
Numbers 12:3
(“Now the man Moses was very meek, above all the men which were upon the face of the earth”.)
In Hebrew the meek means “power under control”
Today "meekness" is "gentleness" or "humility, " largely as a result of the pejorative overtones of weakness and effeminacy now associated with meekness.
If you don’t know the meaning of the words used at the time, you come away with a different understanding of scripture.
On a spiritual level the problem is deception of believers through watering down the truth, which actually impends your ability to believe God because your basing your faith in misapplication.
The over reaching problem is it effects your faith because your believing the wrong stuff.
If I said “you can have two” verses “you can too”, it changes what I am saying altogether, modern translations translate from English to English. The big problem is that english is a bastardized language, we add words and variations of the same words all the time, so a modern translation of the bible misses the mark in many ways.
It is better to teach from the any original language first and no more than the first translation from original language to the next. It preserves what was meant. The most important writings of men are held in Latin, because this language has never changed. That is the reason for the Latin Vulgate originally commissioned by the Catholic church and written by Jerome in 382AD.
The point is, if you want a more satisfactory and compelling experience, if you want to hear from the Holy Spirit more clearly, read the 1611 King James. It will be a challenge initially, but you will come to depend upon it. It will force you to dig deeper and your relationship with God will deepen in ways no article can do justice in explaining. The book also has the Apocrypha in it, the second cannon. Its mostly the completion of the book of Daniel that was not completely translated in the original cannon, the first 66 Books.
I hope this helps….
