And the eye cannot say to the hand, "I have no need of you"; nor again the head to the feet, "I have no need of you."
No, much rather, those members of the body which seem to be weaker are necessary.
1 Corinthians 12:20-22 (NKJV)
If you looked at a sports or business team, you might rank who is the most important person on that team. Or if you asked people what is the most important part on a car, you would probably have a few different answers based on what people think is necessary to make a car function. While in a sense there may be a more important person or a more important part on a car, without the other people on the team, or the other parts in the car, nothing is going to work right.
In 1 Corinthians 12, Paul makes a comparison between the Body of Christ and the human body. In the human body, everyone would agree that the heart is extremely important, but without the lungs the heart would not matter. No rational person would say that there are unimportant parts of their body and, in the same way, no discerning believer would say that there are unimportant parts in the Body of Christ. Every part of the human body is necessary and every part of the Body of Christ is also necessary.
Everyone knows that a pastor is important to a local church, but the person who cleans the church, works in the children's ministry, or serves as an usher is just as important and called by God as the pastor. No matter how unimportant what you are doing may seem to be, it really is important to God and to the Body of Christ. We all need to do our part and take our place in God's Family. No matter who you are, and how unimportant what you do seems to be, you have an important part to play in the Body of Christ!
