Tim Chester in You Can Change:
If anyone is in Christ, he is a new creation; the old has passed away; behold, the new has come! (2 Corinthians 5:17).
When you became a Christian, something amazing happens: you are a new creation. The power of God that made the sun and stars is focused down like a laser into your heart. God steps into the world, as it were, and creates all over again. We’re transformed, reborn, made new.
For God, who said, ‘Let light shine out of of darkness,’ has shone in our hearts to give the light of the knowledge of the glory of God in the face of Jesus Christ. (2 Corinthians 4:6).
At creation God spoke a word into the darkness, and there was light. He spoke a word into the chaos, and there was beauty. And now again God speaks a word through the gospel. He speaks into the darkness of our hearts, and there is light. He speaks into the chaos of our lives, and there is beauty.
