Jesus describes the importance of knowing the only true God as being so important that it is Life eternal:
John 17:3
And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent.
Without knowing Him in every way He has revealed Himself to us we can have no eternal life.. Any revelation of Him must agree with all He has taught us about Himself in His word or we have invented a God made up in the heart of flesh.
He tells us that He is One Lord.. If anyone teaches that God is three they disagree with His revelation. He tells us that He has been God from everlasting and will continue to be God to everlasting. Of anyone teaches that they know how God became God, they again teach the message of a deceitful heart. The Lord Jesus taught us that God is Spirit, and that a Spirit does not have flesh and bone as it was obvious He had. The Holy Spirit through the Apostle Paul teaches is that God is invisible. Anyone that teaches that God is a being of flesh and bone again teaches from their own understanding and will not submit to the righteousness of God.
Mormonism teaches all those errors and yet tries to teach the world that they are the most Bible believing people of all Christ believing people.. Maybe they need to change their AofF to reflect how they really believe the Bible. Not even as far as it is translated correctly but only as far as they can force the square peg of mormonism into the clearly round opening of the Bible.. IHS jim
