We are members of the body of Christ.
One of the misunderstandings of the church today is that there are many churches that belong to Christ. That is simply not true. There is only one church of Christ, the one church that he gave his life for, the body and his bride. You cannot apply for membership or go before some board to be approved. Christ adds you to his church himself (Acts 2:47).
Our identity in Christ is synonymous with the church, his bride. We cannot be one with Christ and not belong to his church (his bride). We are one body with one goal…to fulfill the purposes of God (1 Corinthians 12:12,27).
Examine the word and see what God has to say about the church. If you have obeyed the gospel according to the word of God, then you can be assured of your membership in the one true body of Christ.
