The ROCK........and that rock was Christ.
He is the ROCK, His work is perfect; for all His ways are judgment; a God of truth and without iniquity, just and right is He.
1 Sam 2:2
There is none holy as the Lord; for there is none beside thee; neither is there any ROCK like our God.
2 Sam 22:2
And David said, The Lord is my ROCK, and my fortress and my deliverer; the God of my rock; in him will I trust; He is my shield, and the horn of my salvation, my high tower., and my refuge, my savior; thou savest me from violence. I will call upon the Lord who is worthy to be praised; so shall I be saved from mine enemies.
For in the time of trouble he shall hide me in his pavilion; in the secret of His tabernacle shall He hide me, he shall set me upon a ROCK.
For thou art my ROCK and my fortress; therefore for thy names sake lead me, and guide me.
Therefore whoever heareth these sayings of mine, and doeth them, I will liken him unto a wise man, which built his house upon a rock. And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell not; for it was founded upon a ROCK.
Behold I lay in Zion, a stumblingstone and a ROCK of offence; and whosoever believeth on Him shall not be ashamed.
And did all eat the same spiritual meat; and did all drink the same spiritual drink; for they drank of that spiritual Rock that followed them; and that ROCK WAS CHRIST.
