1 Corinthians 12:12-14 For just as the body is one and has many members, and all the members of the body, though many, are one body, so it is with Christ. For in one Spirit we were all baptized into one body—Jews or Greeks, slaves or free—and all were made to drink of one Spirit. For the body does not consist of one member but of many.
The Church – we are many, but we are one – united in Christ. Though the Church is made up of many individuals, each has his or her own part in making up the body of Christ. Each member is like a part of a body, fulfilling a specific purpose to the greater purpose of the body as a whole.
Why do we gather as a church? To carry out the work of Christ in the world. To bring glory to God. He has commissioned us to go out and do His will and bring about His purposes. When we unite as one, we have strength in numbers, we have unity, we have a greater plan. In our unity, God works in us and through us, just as He works in and through us as individuals.
In each of us, He gives skills and abilities. In the corporate body He puts those skills to work, directing us right where He wants us. Often we pair with someone whose skills complement our own and our effectiveness is doubled, as two strands of rope are far stronger than one (even better with a third – God).
United as a body, we are an unstoppable force in the world for the cause of Christ.
