Six reasons why I believe Christ second coming has already happened. The Bible makes no mention of a gap about Daniel 70 Weeks. Daniel 70 weeks starts in 417BC and finishes 490 years later at His second coming around 66-73AD.

Revelation was written to His servants and the Seven Churches of Asia, it was not written to us 2,000 years later. It was written for us, but not to us. He told the Seven Churches He was coming soon. Rev 1:1

The resurrection took place during Christ generation. Mat 12:41-42 Pharisees were asked who warned you about wrath to come. Mat 3:7 Thessalonian believers were waiting for Christ return from Heaven and being saved from wrath. 1 Th 1.9-10

It was the last Hour. Many people say we have been in the last days for 2,000 years. However John said not only were they in the last days but already the last hour. Five of the kings of Revelation had already fallen, and one is ruling; showing it was first century times. We forget the importance of the first believers and their beliefs.

Faith of some believers was overthrown because of Hymenaeus and Philetus. Thinking this through; if the first century believers thought the resurrection was thousands of years later how could they believe they missed the resurrection, unless the resurrection was going to take place during their life time.
