Ephesians 5:13-14 ESV
But when anything is exposed by the light, it becomes visible, for anything that becomes visible is light. Therefore it says,
“Awake, O sleeper,
and arise from the dead,
and Christ will shine on you.”
The light of Jesus will raise from the dead those who sleep in the darkness. Life and light are imply the nature of God. When Christ shines upon us we become visible as we move from the spiritual graveyard of the world into the house of the Father of lights.
Christ calls into the darkness and shines the light of the way. Becoming visible means walking toward that light.
