Revelation 19:10

Why did John fall down to worship this angel? Some have said he was momentarily confused and thought it was Christ. Others say he was so awed by the scenes of victory and praise that he fell down to worship without thinking. We do not know why John did it, but God uses it to show us angel worship is wrong. Only God is to be worshipped, which is one reason we know Jesus is God. (Matthew 4:10; Hebrews 1:6) The angel told John not to worship him as they were both servants of the Father. Hailey says, "The testimony of Jesus is that truth to which He bore witness (John 18:37), which was the word given to Him from God (John 8:28; John 12:47; John 14:24; Revelation 1:1, et. al.)" Of course, all disciples of Christ hold his testimony in trust, but there may be special reference to the fact that John was one of those intrusted with the charge to deliver that word so others might believe. (John 17:17-20) The very heart of prophecy, or all the Bible, is the testimony of Jesus.
