Ok so Paul gave us a key to see who Jesus is in his fullness. He said the
ROCK that was with Israel was Christ.
Watch this:
Psalms 89:25-26
25 I will set his hand also in the sea, and his right hand in the rivers.
26He shall cry unto me, Thou art
my father,
my God, and
the rock of my salvation.
God speaks in verse 25 about his exaltation of king David. In verse 26 he says how he wants David to call on him.
MY FATHER MY GOD AND THE ROCK of my salvation!
Paul told the Corinthians
THAT ROCK WAS CHRIST!
So again we see in the OT Christ pre existed as God the Father! What a glorious majestic truth!
