There is a vast difference between being in something and actually being it. For example, being an American is vastly different from being in America. Ask anyone who’s gone through getting their citizenship.
So when Paul writes in Ephesians 5 that “…you were once darkness, but now you are light in the Lord,” he’s saying something rather significant. He didn’t say you were once in the dark and now you are in the light. He said you were dark and now you’re light. A vast difference. Being in the dark isn’t as dire as being dark; being in the light isn’t as powerful as being light.
Believers have been changed. They are now light. As believers, it seems we walk too often trying to be in something rather than actually being who we are through the new person our faith in the resurrected power of Jesus has created us to be. Yes, we are to walk in His light. But we are also to be light. Our lives can be much more than just being in the Light.
I am finding the more I take hold of this new identity the more I am light rather than just being in it. I am finding out more “what is acceptable to the Lord” (Ephesians 5:10).
