14 I looked, and there before me was a white cloud, and seated on the cloud was one like a son of man with a crown of gold on his head and a sharp sickle in his hand.
15 Then another angel came out of the temple and called in a loud voice to him who was sitting on the cloud, “Take your sickle and reap, because the time to reap has come, for the harvest of the earth is ripe.”
16 So he who was seated on the cloud swung his sickle over the earth, and the earth was harvested.
-Revelations 14:14-16

Lets break it down..
1. A “son of man” appears.
2. An angel appears.
3. The angel instructs the son of man to do something.
4. The son of man does as he is told.

Here’s the interesting part…
1. Most Christians interpret the son of man on the cloud to be Jesus himself.
If it was Jesus, then don’t Christians(especially those who believe Jesus is God) find it strange that an angel is telling Jesus what to do? 

Also note that immediately after, we read about a second angel instructing a third angel with a sickle to make a harvest of the “grapes” (symbolic of souls, I guess). Both the son of man and the third angel were being instructed to make a harvest.

2. Another thing I’d like to point out, since revelations was written after Jesus walked the earth, so why didn’t the writer just mention the name “Jesus Christ” instead of “son of man”?
