I can't buy it.
To me, the angel speaks in Rev. 22:12-16 quoting Christ. It could be Christ in 18-20. But if one wants to believe in the Trinity, tell me where God was the nine months the Christ child was in Mary's womb? Did Jehovah suckle at a human woman's breast and play in the dirt and get His ass wiped? Was the universe on autopilot? Remember, at that time Satan hadn't been confined to Earth. Would God leave the helm for him to grab when he was still loose?
Also, when Christ says in Matt. 24:36 that even He didn't know when "that day and hour" would come, how then can He be equal to God? How can one part of "you" for example, know something that another part of "you" doesn't know if "you" are "one"? Makes God sound like Rodan on those Japanese sci-fi flicks to believe in the Trinity , doesn't it?
And as far as him saying, so can you turn a blind eye to this and allow your child to die, buddy take that argument (a red herring actually) and shove it where the sun doesn't shine. Now you're getting emotional--fanatical even--and you lose me there. As ex-JW's haven't we gotten beyond "If you don't believe me you're a bad person" yet? But that's the thrust of his argument around half-way through.
