“While you have the light, believe in the light that you may be sons of light” (John 12:36). In Mathew 5:14 Jesus said we are the light of the world. When Christ lives in us we become sources of light to people around us.
Some people are blinded by the light. It is like being in the dark and someone flips on and off a light suddenly. We are aware that a light has been present, but we cannot see to move until our eyes either adjust to the dark again or the light remains on.
That is partly why some respond negatively to believers. Just make sure they are reacting to the light within you and not to any annoying traits of self righteousness.
