THE BIBLE WILL GUIDE US.
The Bible will assist us in making this discovery. It tells us many things which Jesus taught as His Gospel. Any teaching contrary to what He gave cannot be true.
"Though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed." (Galatians 1: 8).
The Gospel which the Savior taught has not changed. It is the same to-day as it was when He dwelt upon the earth.
