That is a very disturbing video. It is a sad state of affairs when speaking about Christ is offensive to people who live in a supposedly "Christian" society....but its not unexpected, (John 15:18-21) especially as the world becomes more secular.
Life is conditional from the Bible's perspective......it was from the start, and it still is now.....but people want the right to do what "they" want to do, regardless of what God says. They see that as their right to express their free will, but want to take the free will of others away from them. This has been the crux of the problem from the beginning I think. Christians had the upper hand for so long that now the boot is on the other foot, we see revenge being enacted. If we all live and let live, as God allows us, then we will offer the Christian message as Jesus told us to, but we will never force our views on anyone. We chose our beliefs and they are free to choose theirs. Informing them about how God feels is our duty but at the end of the day...its their choice and God is their judge.
Was this man disturbing the peace or was he simply disturbing the peace of the protesters just by being there? If his message was peaceful, then why the arrest? Who told those police officers to arrest a man who was not violent but speaking of love? We remember that the apostles were arrested for their preaching too.....people are always going to be offended by the truth because they don't like it.
There is an agenda and it is being upheld by the law enforcers. But who is behind that agenda....? Powerful people in high places I assume....
