The great comparison that Paul gives for a church is the body of Christ. You don't have to be some great intellectual or wise man to understand his analogy. A body must work together, many parts coming together for one purpose, even for a single small thing like lifting an arm in the air.
So too must be the Church of Christ, the body, be dependent on one another to accomplish the task that God has given us. To make disciples of all nations and baptize them in the name of the Father, Son, and Holy Ghost. A healthy church member is one who is dependent on others around them in the church.
There is no one person who is more important than another for a church to fulfill it's mission. And to do so means that:
1. You must be in the body to be in the body. There are no lone ranger church members
2. You must do your own job, the one that God has uniquely gifted you for.
3. You must trust others to do their own job, as God has gifted them.
For even as the body is one and yet has many members, and all the members of the body, though they are many, are one body, so also is Christ. For by one Spirit we were all baptized into one body, whether Jews or Greeks, whether slaves or free, and we were all made to drink of one Spirit. For the body is not one member, but many. If the foot says, "Because I am not a hand, I am not a part of the body," it is not for this reason any the less a part of the body. And if the ear says, "Because I am not an eye, I am not a part of the body," it is not for this reason any the less a part of the body. If the whole body were an eye, where would the hearing be? If the whole were hearing, where would the sense of smell be? But now God has placed the members, each one of them, in the body, just as He desired. If they were all one member, where would the body be?
But now there are many members, but one body. And the eye cannot say to the hand, "I have no need of you"; or again the head to the feet, "I have no need of you." On the contrary, it is much truer that the members of the body which seem to be weaker are necessary; and those members of the body which we deem less honorable, on these we bestow more abundant honor, and our less presentable members become much more presentable,
whereas our more presentable members have no need of it. But God has so composed the body, giving more abundant honor to that member which lacked, so that there may be no division in the body, but that the members may have the same care for one another. And if one member suffers, all the members suffer with it; if one member is honored, all the members rejoice with it. Now you are Christ's body, and individually members of it. 1 Cor 12:12-27
