The lamp of the body is the eye. Therefore, when your eye is good, your whole body also is full of light. (Luke 11:34) Jesus said, I am the light of the world. (John 8:12) Then He said, You are the light of the world. (Matt 5:14) So, let’s unpack this.
Our eye can only be useful to light the way if we use it correctly. When your eye is good means when your eye is sound, working properly. Certain people have an eye for art, for people with talent. They know how to recognize good from bad. When we learn to look at, to take in only what is good, our lives will be filled with light. We have to be able to recognize God and when He is working. We need an eye to see Him. How do we develop that? We ask for wisdom. We ask for His presence to be in us. We ask Him to take out all the darkness inside us. When we clear our lives of darkness, He can fill us fully. We can be His light, not only for ourselves, but for others. We have a responsibility then to be a light set on a hill. That’s not a scary thing. When your life is full of the presence of God, you will be attractive to people living in darkness.
Bottom line, be open to conviction. Be sensitive to knowing that your life is right with God. Repent when you need to and ask for forgiveness. Let Him show you where you are holding onto darkness and get rid of it. The more you do, the more light you carry. The brighter the light, the more fun life you get to have.
