At one point in the desert the Israelites had no water, so Moses asked God for some water.
5 The LORD answered Moses, “Go out in front of the people. Take with you some of the elders of Israel and take in your hand the staff with which you struck the Nile, and go. 6 I will stand there before you by the rock at Horeb. Strike the rock, and water will come out of it for the people to drink.” So Moses did this in the sight of the elders of Israel. 7 And he called the place Massah and Meribah because the Israelites quarreled and because they tested the LORD saying, “Is the LORD among us or not?” Exodus 17:5-7 (NIV)
Paul points out that the rock that was the source of the water is Jesus.
3 They all ate the same spiritual food 4 and drank the same spiritual drink; for they drank from the spiritual rock that accompanied them, and that rock was Christ. 1 Corinthians 10:3-4 (NIV)
Jesus told Peter that He, Jesus, is the rock on which the church is built.
15“But what about you?” he asked. “Who do you say I am?”
16Simon Peter answered, “You are the Messiah, the Son of the living God.”
17 Jesus replied, “Blessed are you, Simon son of Jonah, for this was not revealed to you by flesh and blood, but by my Father in heaven. 18 And I tell you that you are Peter, and on this rock I will build my church, and the gates of Hades will not overcome it. Matthew 16:15-18 (NIV)
The NIV Study Bible, in reference to Matt 16:18 states:
In the Greek “Peter” is petras (“detached stone”) and “rock” is petra (“bedrock”).
The Oxford Dictionary defines bedrock as meaning:
a strong base for something, especially the facts or the principles on which it is based
Peter said that Jesus is the rock, the bedrock, the cornerstone.
4 As you come to him, the living Stone—rejected by humans but chosen by God and precious to him— 5 you also, like living stones, are being built into a spiritual house to be a holy priesthood, offering spiritual sacrifices acceptable to God through Jesus Christ. 6For in Scripture it says:
“See, I lay a stone in Zion, a chosen and precious cornerstone, and the one who trusts in him will never be put to shame.” 1 Peter 2:4-6 (NIV)
Paul again says that Jesus is the rock, the cornerstone.
19 Consequently, you are no longer foreigners and strangers, but fellow citizens with God’s people and also members of his household, 20 built on the foundation of the apostles and prophets, with Christ Jesus himself as the chief cornerstone. Ephesians 2:19-20 (NIV)
What else more is there to say, except:
Jesus Is The Rock and He Rolls My Blues Away
