Many people believe that all religions are true, or that it doesn’t matter what you believe as long as you are a good person. Actually, this is just an excuse for being a bad person, because people cannot be good people if they do not believe the truth. These are walls that people build to protect themselves from the truth.
Jesus explained why people want to protect themselves from the truth:
Everyone who does evil hates the light, and will not come into the light for fear that their deeds will be exposed. (John 3:20)
If you truly love God and your fellow humans you will step into the light and allow your ugly sins to be exposed. God promises that if you repent of your sins and believe in your son that He will cleanse you from all these sins by His power. But He will not do this if you resist the light. You must let your sins be exposed.
Come into the light and be changed!
