For ye were sometimes darkness, but now are ye light in the Lord: walk as children of light:
For once you were darkness, but now you are light in the Lord; walk as children of Light [lead the lives of those native-born to the Light].
for ye were once darkness, but are now light in the Lord: walk as children of light
You were once darkness, but now you are light in the Lord, so live your life as children of light.
For you were darkness, in times past, but now you are light, in the Lord. So then, walk as sons of the light.
