Eph 1:9-10 And he made known to us the mystery of his will according to his good pleasure, which he purposed in Christ, to be put into effect when the times will have reached their fulfillment--to bring all things in heaven and on earth together under one head, even Christ.
As you have probably gathered from my last few posts, I think Daniel 2 has lots to say about the Kingdom of God. I have only one more thing to add before I move on; probably the most important thing about the Kingdom - It's all about Jesus.
Jesus is the King of the Kingdom. The Kingdom of God is all about the coming rule of King Jesus. The vision of Daniel 2 is all about Jesus. He is the rock that was not cut out by human hands that struck the statue in it's legs of Iron. The four Kingdoms represented in the statue in Daniel 2 are the Babylonian, the Medo-Persian, the Greek, and the Roman empires. It was during the Roman empire (the legs of Iron), in the reign of Caesar Augustus that the Kingdom of God invaded this world in the form of a baby laid in a manger. Jesus the promised Christ had arrived.
God's eternal Kingdom plan is centered, like everything else in heaven and on earth, around the person of Jesus. He is the one who humbled himself and became obedient, even to death on a cross, and is now risen from the dead, alive, exalted and seated at the right hand of God in heaven. He is the one "Like a Son of Man" that Daniel saw in chapter 7, who came in glory on the clouds of heaven and was lead into the presence of the Ancient of Days, the one whom all peoples and nations worshiped, the one whose Kingdom will never end.
The Kingdom of God comes when all things, whether in our lives, or in the world, find their rightful place under the feet of King Jesus. His is the Kingdom, his is the power, his is the glory and all authority. And when all things have been put under his feet - he is coming again! Amen, come Lord Jesus.
