Why is the concept of local churches important for Christians?

The local church plays a vital role in the life of believers as it is where the doctrines of Christ are laid in order for all to see. In the sermon, it is emphasized that local churches act as memorials that display the unchanging doctrines that underpin the faith. The church is not merely a gathering spot but a divinely ordained institution that facilitates teaching, worship, and communal support. It serves as a haven for believers, a place where they remind one another of God's promises and nurture spiritual growth, ensuring that these truths are preserved for future generations.
