This promise has enormous implications for every follower of Jesus Christ. “I will build My Church”. Each of the five words in this brief declaration reveals an essential truth of Christian life and service.
First, this promise discloses who will build the church. “I (Jesus) will build my church.” Jesus is the builder of the church, not man. He wants to use us in the process, but He is the builder. Paul understood this arrangement. “According to the grace of God which was given to me, as a wise master builder I have laid the foundation.” (1 Cor 3:10) By the grace of God, Paul served the Lord. As he went about proclaiming Christ, the Lord was using him to lay the foundation (Christ) in lives that were being saved and individual churches that were being started.
Second, Jesus’ promise reveals the certainty of His church being built. “I will (assuredly) build My church.” There is no room for doubt. Jesus will do what He is promising. The only question for us is whether or not we will be available as part of this wondrous process. The Lord wants to make us usable for His work: “sanctified and useful for the Master, prepared for every good work.” (2 Tim 2:21)
Third, this promise indicates the manner in which the Lord wants to work. “I will build( construct) My Church”. As with any construction project, there are both the quantitative and qualitative aspects. The Lord saves souls, adding them to His church in a quantitative increase. “ and the Lord added to the church daily those who were being saved.” (Act 2:47) The Lord also enriches those He saves, bringing to His church qualitative development. “ And with great power, the apostles gave witness to the resurrection of the Lord Jesus. And great grace was upon them all” (Act 4:33)
Fourth, His promise settles the issue of ownership “ I will build My ( Jesus) church.” The church does not belong to the pastor, the church board, or the district office. It is Jesus’ church. He paid the price to redeem us: “the church of God which He purchased with His own blood.” (Act 20:28)
Fifth, this promise specifies exactly what Jesus is going to build. “I will build My church ( His people)”, The church is not a building. The word (church) literally speaks of “a called out people.” “But you are…… His own special people, that you may proclaim the praises of Him who called you out of darkness into His marvellous light; who once were not a people but are now the people of God” (1 Pet 2: 9-10)
