In Revelation 14 we find the last message of God’s mercy to this planet. Three angels present powerful warnings to prepare a people to meet Jesus in His imminent coming.
The prophet saw in vision “another angel fly in the midst of heaven, having the everlasting gospel to preach unto them that dwell on the earth, and to every nation, and kindred, and tongue, and people, saying with a loud voice, Fear God, and give glory to Him; for the hour of His judgment is come; and worship Him that made heaven, and earth, and the sea, and the fountain of waters” (verses 6, 7).
