The universal church is composed of all who truly believe in Christ, but in the last days, a time of widespread apostasy, a remnant has been called out to keep the commandments of God and the faith of Jesus. This remnant announces the arrival of the judgment hour, proclaims salvation through Christ, and heralds the approach of His second advent. This proclamation is symbolized by the three angels of Revelation 14; it coincides with the work of judgment in heaven and results in a work of repentance and reform on earth. Every believer is called to have a personal part in this worldwide witness. (Rev. 12:17; 14:6-12; 18:1-4; 2 Cor. 5:10; Jude 3, 14; 1 Peter 1:16-19; 2 Peter 3:10-14; Rev. 21:1-14.)Obedience does not negate the efficacy of God’s grace. Rather, it defines God’s will for our lives. God writes His law of love on our hearts so that obedience becomes a way of living (Jer. 31:33).
