The difference of course being that Jesus predicted His "coming in clouds" against Jerusalem and the destruction of the temple in that day, to "this generation". He told His disciples "when you see Jerusalem surrounded by armies" that those would be the "days of vengeance". "And they will fall by the edge of the sword, and be led away captive into all nations." Not exactly descriptive of modern warfare. "Then they will see the Son of Man coming in a cloud with power and great glory." (Cf. 1 Tim. 3:16)
At the same time Jesus took His place as the King of the nations, and is bringing all things in subjection ("under His feet") so that "at the end" He will deliver up the kingdom to the Father (1 Cor. 15). That’s all Daniel 7:14 says in retrospect.
And that when He is seen, the Jews would convert (Zech 12:10)
It is amazing what you guys attempt to leave out.
