Now the body is not made up of one part but of many. If the foot should say, "Because I am not a hand, I do not belong to the body," it would not for that reason cease to be part of the body. And if the ear should say, "Because I am not an eye, I do not belong to the body," it would not for that reason cease to be part of the body. If the whole body were an eye, where would the sense of hearing be? If the whole body were an ear, where would the sense of smell be? But in fact God has arranged the parts in the body, every one of them, just as he wanted them to be.
I grew up in a family that loved to play board and card games. We still play and include our kids and grandkids when we all get together. One of our favorites is a card game called Pit. The object is for each player to get all the cards of one grain (oats, corn, flax, wheat, etc.) in his or her hand. The way that is accomplished is by trading with each other. It can get wild and chaotic, as players are shouting "One, two, or three!" Quickly cards are slapped on the table and gobbled up by another player. All are looking for the cards they need.
Sometimes, one player will stop trading and just sit there watching the rest of us. But a curious thing happens. Soon all the trading ends. Why? Because we need the cards in his hand to complete our own.
The body of Christ needs all of us working together as well. Some can't sit on the sideline watching while others are trying to play. It doesn't work. When writing to the church at Corinth, Paul used the example of the human body to illustrate this. We all need to work together just like a physical body for the church to function properly.
It's important to remember that each of us has a role in the body of Christ and we need to fulfill it. Don't let your inaction be a pit fall to others!
