People join many organizations, from civic clubs like Rotary and Lions, to personal development clubs like Toastmasters, to special interest organizations like the P. T. A. It is natural then that most people think about “joining” the church. As strange as it may seem, however, that one cannot “join the church of Christ.” The idea of joining the church carries with it the thought that the church is just like other organizations that you may join at will. The church is unlike any other organization on earth, however, because of its divine origin.

If you cannot join the church, then how do you become a member of the church? The second chapter of Acts describes the beginning of the Lord’s church, on the day of Pentecost, almost two thousand years ago. The last verse of the chapter says, “And the Lord added to the church daily those who were being saved” (Acts 2:47).  Notice that we do not join the church, but the Lord adds those who are saved to the church. Some discount the value of the Lord’s church, and say that it really is unimportant, but the church is the body of Christ. “He [Christ] is the head of the body, the church: who is the beginning, the firstborn from the dead; that in all things he might have the prominence” (Colossians 1:18). The church is so valuable that Christ sacrificed Himself for it. Paul commanded, “Husbands, love your wives, even as Christ also loved the church, and gave himself for it” (Ephesians 5:25).

Since “the Lord added to the church daily those who were being saved” (Acts 2:47), and the church is the body of Christ, and He “gave himself for it,” salvation and the church are intimately tied together. The Lord gives salvation and adds to His church at the same time. The key then, is “What must I do to be saved?” After hearing the sermon on the day of Pentecost, realizing that they had crucified the very Son of God, the multitude gathered in Jerusalem for Pentecost cried out, “Men and brethren, what shall we do?” (Acts 2:37). Their cry showed that they wanted to turn from sin and obey Christ. Peter’s reply was, “Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost” (Acts 2:38).

Those on Pentecost expressed faith in Jesus Christ by the very nature of their question, “Men and brethren, what shall we do?” Peter said, “repent, and be baptized every one of you in the name of Jesus Christ for the remission [forgiveness] of sins.” The response was such that “they that gladly received his word were baptized: and the same day there were added unto them about three thousand souls” (Acts 2:41). Three thousand obeyed Christ in baptism, and the Lord added them to His church. None “joined the church,” but all were added by the Lord. The other conversion accounts in Acts show that each person found salvation by obeying the Lord in baptism, following repentance and faith in Christ. We do not join the church, but when we obey the Lord, He adds us to His church.
