God has worked with Israel and the church at the same time in the past, he does in the present, and he will in the future. Here is a bit on the past.
In the Past
God worked with Israel during the church age in AD 70. Before the death of Jesus during the Old Covenant dispensation, a prophecy given to Israel was predicted concerning God judging Israel with Jerusalem’s destruction, including the temple.
“Now as Jesus was going out of the temple courts and walking away, his disciples came to show him the temple buildings. And he said to them, “Do you see all these things? I tell you the truth, not one stone will be left on another. All will be torn down!” (Matt 24:1–2)
“For the days will come upon you when your enemies will build an embankment against you and surround you and close in on you from every side. They will demolish you–you and your children within your walls–and they will not leave within you one stone on top of another, because you did not recognize the time of your visitation from God.” (Luke 19:43–44)
When did this prophecy to Israel concerning Israel take place? It took place in AD 70 during the church age! Once again it is inconsistent for pretribulation theology to maintain that since the seventy-weeks prophecy in Daniel 9:24–27 given to Israel concerning Israel requires the church to be absent from earth. Yet, here is a clear example where God works with both Israel and the church at the same time. The pretrib assumption that the church must be raptured before the last seven-year period because Daniel’s prophecy was given to Israel has been shown to be inconsistent and deeply erroneous. It is first rank cherry-picking.
