Yes, it is true. Jesus said if they take the coat give them the tunic too. Jesus is profoundly radical by today's standards, by any standard! Tipping over a few tables is about as wild as He chose. He didn't kill. He didn't punch. He forgives. Loves enemies. Wants us to follow Him.  He gives us the Beatitudes to show us what is his way of responding. Very difficult stuff. So, when I say I am a follower of Christ I am aspiring by the Grace of God to conform to Jesus Christ. Currently, I'm not doing so well.
It is still too easy for me to find "a really good reason" to use my weapons of choice, my car horn and a computer key board. Oh and I can give ya a look that will melt ear wax.  And, this radical, Jesus Christ keeps giving us reminders that we are still to enter through the narrow gate. Amend my life according to your will, O Lord.
The quality of my eternity will not be put to a popular vote, nor saved by a loophole in the fine print.  I belong to Jesus Christ, who died for me.
