[4] The Three Angels' messages in verses 6 to 12 form a central feature of the teaching and mission of the Seventh-day Adventist Church: "Make disciples of Jesus Christ who live as His loving witnesses and proclaim to all people the everlasting gospel of the Three Angels’ Messages in preparation for His soon return".
