There’s been no 7 year pact signed as of yet...we would know about it...it would be quite public and the temple would have been rebuilt or in process by now if the pact had been ratified!
The Revelation of Jesus Christ says that there will be a “Great Sign in the Heavens” and give a description of that “sign” in terms that are readily interpreted in terms of long standing constellations. Modern star charting software says that the sign will actually happen, as specified, on September 23-24, 2017.
Biblical scholars who didn’t have star charting software, interpreted it as a “mid-Tribulation” event because it is in Chapter 12, the middle of the Book. However, it is the first “timing” verse in the Book, so it could be at or near the start of the Tribulation.
So if it is a marker for the start of Daniel’s Seventieth Week, then the revealing of the Anti-Christ by his CONFIRMING a covenant wit many, is still in the future. On the other hand, the Iran Deal did have secret side deals that we don’t know about, and Obama could be the Anti-Christ.
The point is that since it has been about 6000 years (or 6 days) since Elohim’s Salvation Plan started, and since it has been about 2000 years (or 2 days) since the final scattering of the Jews, and since they are now returning to the Promised Land, and every nation is arrayed against Israel, and Jerusalem is a great stumbling block, and morality is approaching the levels of Sodom, it is not going to be much longer until He returns.
LOOK BUSY! ;-)
