What role does the church play in a believer's life?

The church plays a crucial role in the life of a believer, as seen in Acts 20:28, where Paul instructs the elders to care for the church of God, which He purchased with His own blood. The church is the community where believers gather to hear the gospel, grow in faith, and support one another. It is the context in which they can watch over their souls and strive towards spiritual maturity. Moreover, the church acts as the pillar and ground of the truth, emphasizing the necessity of being part of a community that faithfully preaches the gospel.
