Do all things without grumbling or disputing, that you may be blameless and innocent, children of God without blemish in the midst of a crooked and twisted generation, among whom you shine as lights in the world… Philippians 2:14-15
God has been speaking to us about being light in the world. Jesus did not say, try and be light in the world. He said: “You are the light of the world.” (Mat 5:14a) His concern was that we will not keep it hidden but that we would shine it out before men. Paul, addresses a similar issue in Philippians 2. He urged them to get rid of things that block the light from shining.
Our grumblings, irritations and frustration prevent the light from shining out of our lives. Rick Warren has written a helpful article for pastors in his pastors.com website. I found it helpful and I am sure you will find it relevant and useful to remove some of our light-blocks.
