Revelation 3:9 (KJV)
9 Behold, I will make them of the synagogue of Satan, which say they are Jews, and are not, but do lie; behold, I will make them to come and worship before thy feet, and to know that I have loved thee.
(Rev. 3:9) is God forcing upon those who are His enemies to acknowledge those that are the real sons of God. It is not worship in that they are coming to worship because they see something that should be worshipped.
The believer is to reject any worship attributed to him as though he is worthy and should be worshipped. satan on the other hand gets worship any way he can.
