As Christians, we believe the Bible is the Word of God without error in the original manuscripts. We trust that God has overseen the preservation of the texts. There are some minor differences among the many available copies, but those differences don’t affect any major doctrines. The extant copies are so numerous and similar that what was in the originals is often discernible. The canon of scripture is closed. So we have a reliable Word that we are commanded to study and live by.
