Who is the Rock?

Scripture says:

Deuteronomy 32:4
King James Version (KJV)
⁴ 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.

And also:

1 Corinthians 10:4
King James Version (KJV)
⁴ And did all drink the same spiritual drink: for they drank of that spiritual Rock that followed them: and that Rock was Christ.

Now consider, God is our Rock and Jesus is the Rock, correct?
Why would Jesus (i.e. God) turn to Simon and say, "You are rock"? Because He wanted all to know that Simon would be he to whom all must turn who want to know God's will. There is a precedent for this in Scripture:

Exodus 7:1
King James Version (KJV)
7 And the Lord said unto Moses, See, I have made thee a god to Pharaoh: and Aaron thy brother shall be thy prophet.

Exodus 18:13-15
King James Version (KJV)
¹³ And it came to pass on the morrow, that Moses sat to judge the people: and the people stood by Moses from the morning unto the evening.¹⁴ And when Moses' father in law saw all that he did to the people, he said, What is this thing that thou doest to the people? why sittest thou thyself alone, and all the people stand by thee from morning unto even?¹⁵ And Moses said unto his father in law, Because the people come unto me to enquire of God:

Exodus 19:9
King James Version (KJV)
⁹ And the Lord said unto Moses, Lo, I come unto thee in a thick cloud, that the people may hear when I speak with thee, and believe thee for ever. And Moses told the words of the people unto the Lord.

God put Moses in a position of authority over the people. Jesus has done the same thing with Simon. God covered Moses with the Cloud, Jesus gave Simon His own name:

John 21:15-17
King James Version (KJV)
¹⁵ So when they had dined, Jesus saith to Simon Peter, Simon, son of Jonas, lovest thou me more than these? He saith unto him, Yea, Lord; thou knowest that I love thee. He saith unto him, Feed my lambs.¹⁶ He saith to him again the second time, Simon, son of Jonas, lovest thou me? He saith unto him, Yea, Lord; thou knowest that I love thee. He saith unto him, Feed my sheep.¹⁷ He saith unto him the third time, Simon, son of Jonas, lovest thou me? Peter was grieved because he said unto him the third time, Lovest thou me? And he said unto him, Lord, thou knowest all things; thou knowest that I love thee. Jesus saith unto him, Feed my sheep.

Jesus has appointed Simon as Shepherd over His flock. And in order to bring this point home, Jesus gave Simon His own name, "Rock" or "Peter".

This is to signify the type of authority which Jesus has given to Simon. He has the authority to bind and loose in the name of God (Matt 16:19).

Sincerely,

De Maria
