"Plastic Knife" people are all around us. Maybe, we are one. People who we or society feel are not worth much, usually because they are not beautiful, rich or useful. Beautiful, rich and useful are the "highest goods" of our society.
God took special care to create these people. We should take extra care to honor them.
The eye cannot say to the hand, "I don't need you!" And the head cannot say to the feet, "I don't need you!" On the contrary, those parts of the body that seem to be weaker are indispensable, and the parts that we think are less honorable we treat with special honor. And the parts that are unpresentable are treated with special modesty, while our presentable parts need no special treatment. But God has put the body together, giving greater honor to the parts that lacked it, so that there should be no division in the body, but that its parts should have equal concern for each other. If one part suffers, every part suffers with it; if one part is honored, every part rejoices with it.
Now you are the body of Christ, and each one of you is a part of it. I Corinthians 12:21-27
Look deeper. See what God's sees and act accordingly today. No one deserves to be overlooked or thrown away.
