Jehovah's Witnesses only worship Jehovah. The Bible says that only God is worthy of our worship and being the recipient of this act from humans is part of what "makes" him God; created things aren't worshipped otherwise it would be idolatry. The Creator is worshipped.
Jehovah's Witnesses do not worship Jesus as they are taught by the Governing Body - who add words to the inspired text of the Bible to back up this doctrine - that Jesus is not Creator but a created thing, also known as Michael the Archangel.
So, my question for Jehovah's Witnesses is: why, when the Bible and Watch Tower Society publications* describe Jesus as being in receipt of worship in heaven and on earth, don't you want to worship him?
