Revelation 19:9-10

9Then the angel said to me, “Write, ‘Blessed are those who are invited to the marriage supper of the Lamb.’ ” And he said to me [further], “These are the true and exact words of God.”

10Then I fell down at his feet to worship him, but he [stopped me and] said to me, “You must not do that; I am a fellow servant with you and your brothers and sisters who have and hold the testimony of Jesus. Worship God [alone]. For the testimony of Jesus is the spirit of prophecy [His life and teaching are the heart of prophecy].”
