Let’s examine the word stone or rock in Hebrew, it is eben and looks like this:
The Aleph, א , is the first character in the Hebrew alphabet and represents God or Heavenly Father.
The Bet, ב , combined with the Nun, ן , means Son in Hebrew or Jesus Christ.
Hence, stone in Hebrew means the Father and the Son.
So when we are told in the New Testament (Luke 6:48) to build our house on a rock and not sand, we should build them on a foundation made up of the Father and the Son.
Another example in the New Testament is when Christ tells Peter in Matt 16:18:
“And I say also unto thee, That thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it.”
Interestingly, Peter, in Greek, means rock. Hence, the Church will be built upon a rock or upon the Father and the Son, the source of all revelation with Peter, a rock, as President of the Church, who represents the Father and the Son here on earth.
