Here's today's Gospel reading from Luke 14:
On a sabbath Jesus went to dine at the home of one of the leading Pharisees. He said to the host who invited him, "When you hold a lunch or a dinner, do not invite your friends or your brothers or sisters or your relatives or your wealthy neighbors, in case they may invite you back and you have repayment. Rather, when you hold a banquet, invite the poor, the crippled, the lame, the blind; blessed indeed will you be because of their inability to repay you. For you will be repaid at the resurrection of the righteous."
The clear lesson here is that when we are being kind to others, we should do it for the Lord's sake and not expect to receive repayment. This would be true charity. Do anything to get ourselves recognized or appreciated is a sin that is often easily overlooked.
