There are many cults in the world today. The three major ones are Mormonism, Jehovah's Witnesses and Christian Science. This section will deal with the way in which these main cults depart from the truth. Essentially, they attack the Word of God, stating that the Bible is incomplete by introducing error in the form of extra biblical "revelation".

True Christianity has a standard. That standard is the Holy Bible. God has said in the book of Revelation 22:18-19, "For I testify unto every man that heareth the words of the prophecy of this book, If any man shall add unto these things, God shall add unto him the plagues that are written in this book:" and "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".
