Watchman Nee emphasizes the scriptural basis for the formation of local churches, asserting that a church is simply a group of believers in a specific locality who have received Christ. He argues that membership in a local church is based solely on being a believer and residing in that locality, without any additional conditions or denominational barriers. Nee warns against divisions based on leaders, doctrines, or social distinctions, stressing that true unity comes from the indwelling Spirit of Christ in all believers. He encourages Christians to recognize their oneness in the Spirit and to maintain fellowship with all believers in their locality, regardless of differences. Ultimately, he calls for a return to the biblical understanding of the church as a local assembly of all God's children in a given area.
