Paul gives God’s church a warring, “For if he who comes preaches another Jesus whom we have not preached, or if you receive a different spirit which you have not received, or a different gospel which you have not accepted—you may well put up with it!” (2 Corinthians 11:4).
Throughout the ages, God’s truths have been clear. God’s definition and explanation of sin is clear (Matt. 5:21, 22, 27, 28; 1 John 3:4). The path to come to Christ for salvation is clear (Isa. 55:1; Rev. 22:17). The way to receiving righteousness is clear (John 3:19–21). God’s promises for receiving His blessings are clear (2 Cor. 7:1). Therefore, there is no reason to have new doctrines. God’s truths are eternal as He is eternal.
Jesus demonstrated His complete confidence in the unchanging truths and doctrines of the Scripture when He fought the devil with the words “It is written” (Matthew 4:4,7, 10). Christ’s trust in His Father and His knowledge of His will were founded on the Scriptures. In this lay the secret of His strength to meet every temptation.
The Lord warns against deliberate changes in His truths, “For I testify to everyone who hears the words of the prophecy of this book: If anyone adds to these things, God will add to him the plagues that are written in this book; and if anyone takes away from the words of the book of this prophecy, God shall take away his part from the Book of Life, from the holy city, and from the things which are written in this book” (Revelation 22:18, 19).
The ultimate test of all new doctrines is given by the prophet Isaiah “To the law and to the testimony! If they do not speak according to this word, it is because there is no light in them.” (Isaiah 8:20). Isaiah directs men to the Word of God as the only standard of truth and the guide to right living. Whatever men may speak that is not in harmony with what has been already revealed, then, they have “no light” in them (Isaiah 50:10, 11).
