Whatsoever God says unto you, do it and take heed that you let no
one lead you astray.
The voices of the many only leads to confusion and God is not the
author of confusion.
If you want to learn truth, God, Himself will teach you by His
Spirit of truth, the Holy Ghost.
When the spirit of Truth has come, He will teach you all things and
bring to your mind (remembrance) all things both written and unwritten
that was said by Jesus Christ.
Remember what John the Apostle said, If every one of these things
that Jesus said and did should be written, not even the world itself
could hold the books that would have to be written.
Yet Jesus said, Heaven and earth will pass away but my words will
never pass away.
The reservoir of all truth including the words of Christ is the Holy
Ghost.
