"The God of heaven will set up a kingdom"
In Daniel 2:31-45 the prophet talks about the king's dream, the statue of gold, silver, bronze, iron and clay as the different kingdoms which were and were to come.
And then he mentions a rock that struck the statute, which are all the different kingdoms and crushed them to powder which the wind swept away. That Rock became "a huge mountain and filled the whole earth".
Daniel 2:44-45a says,
“In the time of those kings, the God of heaven will set up a kingdom that will never be destroyed, nor will it be left to another people. It will crush all those kingdoms and bring them to an end, but it will itself endure forever. This is the meaning of the vision of the rock cut out of a mountain, but not by human hands—a rock that broke the iron, the bronze, the clay, the silver and the gold to pieces."
In Daniel 2:34a it says, "While you were watching, a rock was cut out, but not by human hands." And that's the same Rock that Isaiah 28:16 talks about as being laid not by human hands but by the Sovereign Lord, "So this is what the Sovereign Lord says: “See, I lay a stone in Zion, a tested stone, a precious cornerstone for a sure foundation; the one who relies on it will never be stricken with panic." And in Ephesians 2:20 we read that the church or the kingdom of God is "built on the foundation of the apostles and prophets, with Christ Jesus himself as the chief cornerstone."
So it is clear that from these passages that "the rock that struck the statue became a huge mountain and filled the whole earth." (Daniel 2:35c) is none other than Jesus Christ.
From Daniel 2:44 we read that "The God of heaven will set up a kingdom that will never be destroyed...and will itself endure forever" because it is built on his Son Jesus Christ. He is the rock on which we are built on which the gates of hell will not prevail against, and "the one who relies on it will never be stricken with panic." (From Isaiah 28:16)
Napoleon Bonaparte said, "I know men; and I tell you that Jesus Christ is no mere man. Between Him and every person in the world there is no possible term of comparison. Alexander, Caesar, Charlemagne, and I have founded empires. But on what did we rest the creations of our genius? Upon force. Jesus Christ founded His empire upon love; and at this hour millions of men would die for him."
