The document discusses the remnant church and its mission. It defines the remnant as those who keep God's commandments and have faith in Jesus during a time of widespread apostasy. The remnant's mission is to proclaim the arrival of judgment, salvation through Christ, and Christ's second coming. This proclamation coincides with judgment in heaven and repentance on earth, as symbolized by the three angels' messages in Revelation 14. The remnant heralds the establishment of God's kingdom and new heaven/earth. All believers are called to participate in this global witness.
