A temple is a divine dwelling place, the habitation of deity. It’s a special place because God’s awesome. Who wouldn’t want to stop by God’s house, and pay Him a visit every now and then? It sounds nice at first, but there’s a problem lurking here.
Thinking God has a house, a place we can go to be closer to Him, is also thinking that in every other place we’re farther away from Him. If we know where He is, we can get away from Him and keep Him at a distance. That’s a problem.
Fact is, God’s everywhere, all the time. (Ps 139:7) There isn’t any place He isn’t, where we can be any closer to Him or farther away from Him. He’s in our face, and we’re in His, every moment of every day. There’s no place to hide.
The real temple of the living God is the human heart, mind and soul. God dwells within each believer (1Co 6:19), and in a particularly powerful way, though believers united together in Him as a living sacrifice. (1Co 3:16) God doesn’t need, or even want, a house separate from us (Ac 17:24); there’l be no temple in eternity. (Re 21:22)
