God has called a bunch of people out of body of humanity. The ones that have faithfully responded to that call have become the called out ones, the church. The word, church, does not mean, ‘bunch of religious people”. It means, “the called out ones”.
Every group of people functions in a different way. The church functions in certain way that reflects God’s purpose for the church. It functions like a body (Romans 12:5, 1 Corinthians 12:13,27, Ephesians 1;22,23, 5:23 etc.). That’s the biblical description of what the church is and how it functions.
The scripture never says the church is like a body. It says that it is a body, in fact, the body. By its very nature, given to it by Christ, it has a head (Christ himself). It has a different organs, limbs and parts (members). It has a need for food (the Word). Every part of the body functions together for an overall purpose (to do God’s will). There is a dependant relationship between all the parts of the bodies. When those relationships are weakened the whole body suffers from ill health.
Every body has a blood system that carries life to all the parts of the body. In the body of Christ, the church, that blood is the blood of Jesus. It is through the blood of Jesus that we are saved. When God called us out of the world He did so on the basis of the death of Jesus. To be able to make the call, God had to choose to pay the price for the call.
Given all this, I have one question. What is the heart of the church? In every body there is a heart. In the body of Christ, what is that heart?
