In the movie "Field of Dreams" we heard words that have since been immortalized and even used in Christian circles: "If you build it, he will come." This was about building a baseball diamond in the middle of the Iowa cornfields. When the father finally emerged through the corn rows and played catch with his son, tears came to my eyes. What a meaningful scene. I could not help but think of my dad, playing ball with me.
As beautiful as that is, there is no meaningful analogy between the movie and the father's appearance, and the kingdom of God and God's appearing presence. Spiritually, it's not true that, "If you build it [something, whatever], then God will show up."
But... When God comes, he will build it.
Here God's earth-shattering, empowering presence comes first. Wherever God shows up he builds his kingdom, on earth, as it is in heaven. Jesus-followers are invited to join him in The Great Edifying, The Great Upbuilding.
If He comes, he will build it. You will join him in the labor, empowered by God's Spirit.
