I believe the whole issue of Bible versions hinges on this point. Did God preserve His Word? I could multiply verses that indicate He did preserve every word. If God did not preserve His Word, then we don't have a Bible. We just have book full of errors that have some of God's words in it, and we're not really sure which words were God-breathed, since the originals don't exist. It is unreasonable to believe that a sovereign, all-powerful, loving God would not keep His Word. Matthew 24:35 Heaven and earth shall pass away, but my words shall not pass away.
