Some are no match for the fast paced technology of the world today. Some cannot get from under the iron shoe of oppression and injustice. That one man with his grocery cart moving from place to place with no visible means of support represents the throngs of people who are being ignored by those of us who have been blessed with God's abundance. He represents those who fall through the cracks of government programs that sometimes put more in to red tape than in helping people. He represents those the Church is called to show compassion, as did Jesus to the crowds he met almost every where he went.
Compassion is in the call.
Now for sure there are some who run a game on the public. There are some who make a living coning the unsuspecting guilt-ridden public. They are out there in the crowd. And they will sometime get over on us. But that cannot be the reason we don't do anything at all.
