Why did God create? What was his purpose, his reason? In Isaiah 45:18 God himself answers that question.
“For this is what the Lord says—he who created the heavens, he is God; he who fashioned and made the earth, he founded it; he did not create it to be empty, but formed it to be inhabited— he says: ‘I am the Lord, and there is no other.'”
God created the heavens and the earth to be inhabited. Yet what does he desire it to be inhabited with? It is only as we continue to read the Biblical narrative that the answer unfolds itself: he longs for his creation to be filled with his glory, his manifest presence. This is why he says later, “For the earth will be filled with the knowledge of the glory of the Lord, as the waters cover the sea” (Hab. 2:14, NASB95).
Along the same lines, the seraphim in Isaiah call to one another and say, “Holy, Holy, Holy, is the Lord of hosts, the whole earth is full of His glory” (Isaiah 6:3, NASB95). Creation is a revelation of God’s glory. John Calvin, one of the church’s foremost theologians, referred to the world as the “theater” for God’s glory.
Yet presently there is still more of God’s glory to be revealed in creation. That is why Habakkuk said the earth would be filled with the “knowledge of the glory.” At the moment heaven is the primary place of the Lord’s glory. This is why we pray, “Our Father who is in heaven.” But the Father’s ultimate intention is that his glory will cover the earth as “the waters cover the sea” (Hab. 2:14). His purpose is that his kingdom will come and his will is done on earth as it is in heaven (Matt. 6:10). The heavens and the earth are meant to be a sanctuary for God. It was not good for God to be alone: he desired the earth to be filled with men and women who could appreciate, honour and experience his glory. Even more spectacular, he created us to be the ultimate fulfilment of his sanctuary—the place where he dwells.
Prayer: Father, you created me to dwell in me. I have been made to be your home. May you feel welcomed and valued in me. Today, fill me with your glory. And my prayer is not for myself alone, I pray that you would cover the earth with your glory as the waters cover the sea.
