The New Testament church was established by Jesus Christ and empowered by the Holy Spirit. Its identity was not rooted in a particular nation, ethnicity, building, or religious institution. It was simply a gathering of believers united by their faith in Jesus as the Messiah. Before His crucifixion, the Son of God promised that the Holy Spirit would continue teaching and guiding His followers into truth.

That promise was fulfilled on the Day of Pentecost. As Jews from many regions gathered in Jerusalem, the Holy Spirit fell upon the disciples in the upper room, they spoke in various languages and spilled outside. Peter boldly declared the crucifixion and resurrection of Jesus Christ and called those listening to repent and be baptized. Approximately 3,000 men responded, marking a dramatic expansion of the church.

The Jerusalem believers devoted themselves to the apostles’ doctrine, fellowship, prayer, and breaking of bread. They met in homes and on the temple grounds, and voluntarily shared resources to care for those in need. The apostles continued preaching despite opposition from the ungodly Jewish religious authorities.

But Jesus had commanded His disciples to proclaim the Gospel beyond Jerusalem. Following the martyrdom of Stephen, violent persecution scattered believers throughout Judea and Samaria. Rather than silencing the church, this opposition helped spread its message. Philip preached Christ in Samaria, where many believed and were baptized. Later, guided by the Holy Spirit, he explained the prophecy of Isaiah to an Ethiopian official, who also believed and was baptized.

The same commission is still in effect today. Remain faithful to Christ’s teachings, follow the Holy Spirit, and proclaim the Gospel to every nation.
