Mark 5:18-20 (NIV)
As Jesus was getting into the boat, the man who had been demon-possessed begged to go with him. [19] Jesus did not let him, but said, “Go home to your family and tell them how much the Lord has done for you, and how he has had mercy on you.” [20] So the man went away and began to tell in the Decapolis how much Jesus had done for him. And all the people were amazed.

I would have wanted to follow Jesus like a puppy dog. But Jesus tells the man to go home.

Think of 5 of the worst humans you know–personally or historically. Now imagine them come home smelling good and acting like Mother Teresa.

That is what God can do.

And it is indeed amazing.
