"wedding of the Lamb"

Revelation 19:6-10 Then I heard what sounded like a great multitude, like the roar of rushing waters and like loud peals of thunder, shouting:
   "Hallelujah!
      For our Lord God Almighty reigns.
 Let us rejoice and be glad
      and give him glory!
   For the wedding of the Lamb has come,
      and his bride has made herself ready.
 Fine linen, bright and clean,
      was given her to wear." (Fine linen stands for the righteous acts of the saints.)

 Then the angel said to me, "Write: 'Blessed are those who are invited to the wedding supper of the Lamb!' " And he added, "These are the true words of God."

 At this I fell at his feet to worship him. But he said to me, "Do not do it! I am a fellow servant with you and with your brothers who hold to the testimony of Jesus. Worship God! For the testimony of Jesus is the spirit of prophecy."

It is normal for even a men of God to react in reverence at the sight of an Angel, but we only worship God.

Revelation 22:8
I, John, am the one who heard and saw these things. And when I had heard and seen them, I fell down to worship at the feet of the angel who had been showing them to me.

Judges 13:20 As the flame blazed up from the altar toward heaven, the angel of the LORD ascended in the flame. Seeing this, Manoah and his wife fell with their faces to the ground.
