"Go away from me"

Today's gospel reading made me feel kind of sick ... Luke 13:22-30 ...

Jesus went through one town and village after another, teaching as he made his way to Jerusalem. Someone asked him, ‘Lord, will only a few be saved?’ He said to them, ‘Strive to enter through the narrow door; for many, I tell you, will try to enter and will not be able. When once the owner of the house has got up and shut the door, and you begin to stand outside and to knock at the door, saying, “Lord, open to us”, then in reply he will say to you, “I do not know where you come from.” Then you will begin to say, “We ate and drank with you, and you taught in our streets.” But he will say, “I do not know where you come from; go away from me, all you evildoers!” There will be weeping and gnashing of teeth when you see Abraham and Isaac and Jacob and all the prophets in the kingdom of God, and you yourselves thrown out.

I guess this is about maintaining going-to-heaven exclusivity standards, but I wish the way was wide, not narrow.
