One of the most important functions of the church is evangelism, sharing the good news of Jesus Christ in order to make more disciples for his kingdom (Matthew 28:18–20). This gospel witness to the world will result in the end of the world and the second advent of Jesus (Matthew 24:14). We, the members of the Grace Seventh-day Adventist® Church, see this as our highest calling.
And Jesus came and said to them, 'All authority in heaven and on earth has been given to me. Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you. And behold, I am with you always, to the end of the age.'
Moreover, in the time of the end of Earth's history, the three messages of Revelation 14:6–12 is to be proclaimed throughout the world as an eternal gospel witness to Jesus and his biblical truth and as a warning about the coming last-day deceptions. The purpose of this threefold message is to prepare a people to meet their Savior and Lord, Jesus Christ, when he returns—the "blessed hope" (Titus 2:13).
Then I saw another angel flying directly overhead, with an eternal gospel to proclaim to those who dwell on earth, to every nation and tribe and language and people. And he said with a loud voice, 'Fear God and give him glory, because the hour of his judgment has come, and worship him who made heaven and earth, the sea and the springs of water.'
Another angel, a second, followed, saying, 'Fallen, fallen is Babylon the great, she who made all nations drink the wine of the passion of her sexual immorality.'
And another angel, a third, followed them, saying with a loud voice, 'If anyone worships the beast and its image and receives a mark on his forehead or on his hand, he also will drink the wine of God’s wrath, poured full strength into the cup of his anger, and he will be tormented with fire and sulfur in the presence of the holy angels and in the presence of the Lamb. And the smoke of their torment goes up forever and ever, and they have no rest, day or night, these worshipers of the beast and its image, and whoever receives the mark of its name.'
Here is a call for the endurance of the saints, those who keep the commandments of God and their faith in Jesus.
