If only You would rend the heavens and come down, so that mountains would quake at Your presence, — Isaiah 64:1

The same God who spoke light into existence at creation has shined in your heart. He gives the light of the knowledge of the glory of God in the face of Jesus Christ. That's a creation-scale miracle — the spiritual equivalent of light appearing where there was only darkness. You didn't find the light; the light found you. And now the One who said 'Let light shine out of darkness' lives in you, and you get to reflect His glory.
