"And if any man shall take away from the words of the book of this prophecy, God shall take away his part out of the book of life, and out of the holy city, and from the things which are written in this book." (Revelation 22:19)
This final testimony and warning of Christ to those who profess to be His followers is a clear command not to either augment (Revelation 22:18) or dilute the inspired "words" (not just "thoughts") of the Bible. There are many people in the various cults following some leader who think he or she has received some new inspired word from God. That is very unwise. But it is usually certain leaders in the mainline denominations who presumptuously either cull out or explain away those Bible verses they consider unscientific or offensive in some way. That is even more dangerous, for those whose names are not found "in the book of life" will be "cast into the lake of fire" (Revelation 20:15).
Whether men believe it or not, the Bible is the inerrant Word of God. It is true that any two Christians may interpret certain passages in different ways. But they won't be too far apart if they believe the Bible to be the inerrant, understandable, inspired Word of God, especially if they really believe that God is able to say what He means. The Bible authors do occasionally use figurative language, of course, in which case any symbols are usually explained in context. When the writer clearly intends to be understood literally, as in the first chapter of Genesis for example, it is dangerous to impose some metaphorical meaning on the passage because of outside considerations. This seems to be what Paul called "handling the word of God deceitfully" (2 Corinthians 4:2) and can become a very slippery slope for those who choose that broad and easy way. It will be easier at Christ's judgment seat to explain why we believed God than why we believed men who questioned God. HMM
