The building is not the church; it is merely what accommodates the church. The church is the coming together of every single believer. The word "church" in Greek is "Ecclesia," consisting of two words: "Ek," which means to pull out, and "Kaleo," meaning to call. When you combine these two words, it means "the called-out ones." So, the church is the "called-out ones," called out of darkness into the light of Christ.
The church is defined as an interdependent, life-pulsating people indwelled by the presence of a resurrected and reigning Christ. The word "interdependent" signifies that you cannot be the church by yourself. For us to be a church, we must recognise our own deficiencies and understand that our lack can be someone else’s strength. Therefore, we must depend on each other’s strengths so that together we can be strong.
The church is also referred to as the Body of Christ. Christ is the head of the church, and we are the body. The head is already established, waiting for the body to mature. We are growing into the head of Christ; Christ is not growing into our body. Christ, the head, is waiting for the church to reach maturity.
