Different versions of the Bible often present different doctrines. God's Word says
"Jesus Christ the same yesterday, and to day, and for ever" (HEBREWS 13:8). Jesus Christ is the Living Word of God, therefore we know that God's words will not change. In our assembly we use the King James Version (KJV) which is otherwise known as the Authorized Version (AV). Examples of how the King James Bible and the New International Version (NIV) put forth different doctrine can be seen in Does It Make A Difference If I Use The KJV Or The NIV?
2 TIMOTHY 3:16 says
"All scripture is given by inspiration of God, and it is profitable for doctrine, for reproof, for correction, for instruction in righteousness."
"Every word of God is pure ..." (PROVERBS 30:5). Despite these Scriptures, the NIV and other modern versions leave out some words, and even whole verses. Why Do You Prefer to Use the KJV Rather than Modern Versions Like the NIV? shows the differences between the KJV and NIV in their source material and in translation method, demonstrating the superior worth of the KJV. To study the subject of Bible versions in greater depth we recommend two excellent books written by Gail Riplinger: New Age Bible Versions and The Language of the King James Bible. Gail Riplinger has researched this topic in much detail and both exposed the corruption of the newer versions as well as demonstrated the inspiration of the King James Version.
Some people wonder why the Christian Bible does not contain as many books as the Catholic one. There have also been other writings found, of which authorship is attributed to Biblical people. The subject of why these extra books are not included in the Bible is examined briefly in Should the Forgotten Books be a Part of Our Scriptures?
