For at one time you were darkness, but now you are light in the Lord. Walk as children of light
Have you ever noticed that sin happens in the dark? Darkness is the absence of light. Where there is no light sin abounds.
Light is referred to as knowledge, truth and holiness. When light shines in the darkness it overcomes it and there is no more darkness. This is what Paul is meaning as he says, “Walk as children of light.”
Before you made a decision to believe and follow Jesus you were living in darkness. But now, you have overcome the darkness with the light of Christ.
This verse begins in the past tense, “you were darkness.” In the first few verses of Ephesians chapter 2 Paul says, “And you were dead in the trespasses and sins in which you once walked, following the course of this world, following the prince of the power of the air, the spirit that is now at work in the sons of disobedience— among whom we all once lived in the passions of our flesh, carrying out the desires of the body and the mind, and were by nature children of wrath, like the rest of mankind.”
But now that Christ lives in you, you are light and there is no darkness is in you. The light that is now inside of you has overcome the darkness that once controlled you. To live as a child of light means to walk according to what is acceptable to the Lord which is goodness, righteousness, and truth (vs. 9-10).
Lord, let me be the light in this dark world. Help me to shine bright so that it brings others to the light. Thank You for being my Light.
