Each of us is a kind of sovereign lord and, like all rulers, we have a territory we rule over. That territory is the inner space where we step back from the world to make decisions, imagine and create. Not even God himself trespasses there. As previously mentioned, he waits for us to invite him in. Having such authority is part of what it means to be created in God’s image.
We are, however, only an image of God, not God himself. As the picture projected onto a screen needs light in order to be seen, so we are only clearly the image of God when we invite the Light into this sacred inner space. When we do, our innermost being becomes the Holy of Holies, that place where God dwelt in Israel’s tabernacle in the wilderness.
In Hebrews 9:19-28 the writer speaks of this tabernacle being a picture of heaven and then makes a most curious assertion–heaven itself needs to be purified! How can this be? I thought heaven by definition was pure. Whatever the mystery contained in all this, one thing is certain, there is a direct relationship between our deepest, truest nature and the heavenly realm. For our inner being to be cleansed, heaven needs to be cleansed. So Hebrews speaks virtually interchangeably of both heaven and the hearts of believers being sprinkled with the blood of Christ. c.f. Hebrews 10:22
So then, when we have invited Christ into our inner sanctuary, our hearts become a beachhead, part of God’s sovereign kingdom upon earth. We are called to protect this holy territory and to extend it out into the world by letting his love reign in our lives–family, work, community etc. The heavenly kingdom comes as God’s will is done on earth as it is in heaven.
