A relationship is like a house. When a light bulb burns out, you don't go and buy a new house, you fix the light bulb.
Has the light gone out in any of the important relationships in your life? Meaningful relationships require a commitment. Don't just walk away in the darkness. Identify the problem and work on fixing it. Ask God to shed a little light on it for you. Could it be your relationship with God that needs your attention? Regardless, starting with prayer will help you flip the switch back on.
Again Jesus spoke to them, saying, "I am the light of the world. Whoever follows me will not walk in darkness, but will have the light of life."
