Jesus told his disciples “I will build my church; and the gates of hell shall not prevail against it” (Matthew 16:18). Have you ever wondered what he meant by that? He obviously was not speaking of a building as we often make use of the term today (e.g., did you go to church?). What then exactly is he building? How is he building it? Consider the following:
We read in Paul’s letter to the Colossian believers about the “body of Christ”. “And 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 preeminence” (Colossians 1:18; emphasis added). This body is a living organism comprised exclusively of those made spiritually alive through the new birth and added to the body by the Lord himself. “And the Lord added to the church daily such as should be saved” (Acts 2:47).
Those who are saved are those who have put their faith in Jesus Christ having believed the gospel of God’s grace. “For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: not of works, lest any man should boast” (Ephesians 2:8-9). This faith comes through believing God’s word. “In whom [Christ] ye also trusted, after that ye heard the word of truth, the gospel of your salvation” (Ephesians 1:13).
Summarily, Christ adds to his body (builds his church) those who are given spiritual life through receiving the gospel. This new life is the work of the Spirit of God through his word. “Ye have purified your souls in obeying the truth through the Spirit…being born again…by the word of God, which liveth and abideth forever” (I Peter 1:22-23). Such are added to the body one person at a time.
We have a perfect illustration of Christ building his church in the record of Philip and the Ethiopian eunuch in Acts 8. The angel of the Lord initiated this work of salvation by first directing Philip to a desert in Gaza (Acts 8:26). There Philip found “a man of Ethiopia, an eunuch of great authority…sitting in his chariot” (Acts 8:27-28). The eunuch was reading the word of God from Isaiah, the prophet. Philip was then instructed by the Spirit to join the man in his chariot.
The Lord opened the door for Philip to explain the Scripture to the eunuch. “He was led as a sheep to the slaughter; and like a lamb dumb before his shearer, so opened he not his mouth…for his life is taken from the earth” (Isaiah 53:7-8). Then Philip “began at the same scripture, and preached unto him Jesus” (Acts 8:35).
The Ethiopian eunuch then put his faith in Christ. “I believe that Jesus Christ is the Son of God” (Acts 8:37). His salvation came about by the work of the Spirit through the ministry of the word of God resulting in faith in Jesus Christ. This is how Christ builds his church – then and now. Have you believed? Are you a part of Christ’s body, the church?
