Read Luke 14 today.

Jesus attended a dinner, which presented an opportunity to teach about many things. Since the dinner was on the sabbath, the issue of what one was permitted to do on the sabbath was one of the topics. (One of the things that seems odd to me in this story is that the dinner was on the sabbath. I am not familiar with all the rules relative to keeping the sabbath, but whenever we have had people over for dinner, it has been more work rather than less.)
Jesus spoke about those to whom invitations should be extended. He said to invite those who would not be able to ‘return the favor.’ This is harder to do because we may not know anyone who would fit into this category. We may need to extend our relationships to some new people. Might this be one of the reasons Jesus said to so this?
Additionally, when we invite those who cannot pay us back, we are more likely to be doing it for those we invite rather than for ourselves. Sometimes our invitations have selfish motives under the surface. Who would be included on your guest list? Who would be excluded?
Luke 14:12-14 NLT
Then he turned to his host. “When you put on a luncheon or a banquet,” he said, “don’t invite your friends, brothers, relatives, and rich neighbors. For they will invite you back, and that will be your only reward. [13] Instead, invite the poor, the crippled, the lame, and the blind. [14] Then at the resurrection of the righteous, God will reward you for inviting those who could not repay you.”
