Christianity is a rebellion. Christianity was founded by the greatest rebel of all time, Jesus Christ. He turned the entire planet on its head. He turned a religious system completely upside down. He went into the culture and told them they were wrong, and they crucified him for it. Why should we be any different?
We are all spiritual beings wrapped in flesh wrapping paper. Christians are the ones who realize it, and serve a different Kingdom other than the world. We have rebelled against the flesh. Christians have repented, because the Kingdom of God is at hand.
Always remember, Pass the Salt.
