The Prophet David foretold, by the Spirit of prophesy, that preaching the salvation will reach to the entire world by the holy twelve disciples and seventy apostles. He said, “Their line has gone out through all the earth, and their words to the end of the world” (Ps 19:4). One of the events of the Old Testament also referred to their number; when Moses led his people to Elim, where there were twelve wells of water and seventy palm trees; so they camped there by the waters (Exodus 15:27). The twelve disciples in number match that of the tribes of Israel, while the number of the apostles matches that of the elders selected by Moses (Num 11:16-25).
During the time of the Apostles, the Early Church was very strong because it was a true Church of worship. The whole congregation was worshiping with one accord, and not one was missing. “These all continued with one accord in prayer and supplication, with the women and Mary the mother of Jesus, and with His brothers.” (Acts 1:14) “And they continued steadfastly in the apostles’ doctrine and fellowship, in the breaking of bread, and in prayers.” (Acts 2:42) “And continuing daily with one accord in the temple.” (Acts 2:46) “Now the multitude of those who believed were of one heart and one soul.” (Acts 4:32)
The Importance of the Church to the Believer
According to the apostolic concepts, the church is the house of God, the pillar and the ground of the truth (1 Tim. 3:15). Everyone should hear from her and anyone who refuses to hear the church will be like a heathen and a tax collector (Matt. 8:17). Church is the bride of Christ, who came out from His pierced side on the cross, as Eve came out of Adam’s side while he was asleep. Church is the source of gifts and provider of sacraments for the believer to live as a member of that one body of Christ. Church is the gate of heaven. This indicates that there is no salvation outside the church.
