The theme of heaven coming to earth is a theme throughout the Scripture. The end of the Bible predicts heaven coming to earth as the heavenly city descends to earth (Revelation 21). This means earth will ultimately reflect what heaven now is in many ways. Ephesians 1 tells us how this is going to happen – Jesus is going to unite things in heaven and earth.
9making known to us the mystery of his will, according to his purpose, which he set forth in Christ 10as a plan for the fullness of time, to unite all things in him, things in heaven and things on earth. (Ephesians 1:9–10 ESV)
Jesus is a real man so He longs for the earth. It is easy for us to forget that, though He sits at the right hand of God, Jesus remains a real human being. He is completely human and, as all human beings, longs for the earth. Just as we deeply long for the earth – a restored earth – more than we desire an ethereal heaven, so also Jesus misses the earth. The Bible tells us that our bodies are taken from the earth meaning we are inseparably bound to the earth. Jesus, as a real human, is physically connected to the earth.
At the same time, Jesus is fully God. He has a divine nature and that also gives Him divine desires. That means He longs for the realm of heaven. He longs for the reality of Revelation 4 and 5. This is His natural habitat; His natural abode. Jesus is a man so He longs to dwell on the earth, but He is also God so He longs for the activity of heaven. The divine solution is that Jesus will bring both together. He will rule on the earth, but He will also fill the earth with the night and day adoration of heaven.
This is just one component of why Paul tells us that heaven and earth are united in Jesus. Jesus is the divine intersection between earth and heaven. He is the one that unites the two into one reality. This is precisely what Revelation 5 predicts. The Lamb in the middle of the throne is the very center of heaven’s adoration. At the same time that Lamb is a man restoring the calling of human beings and fully committed to human beings walking in that calling on the earth. All of this tells us precisely what God has planned for the earth.
