Thats where I think I am too.. but the Pastor is doing a great job of being neutral in presenting all the different eschatological position .
Before you conclude that God is done with Israel look at Jeremiah 23:5-6 and Romans 11:25-28. Also, consider Rev 19:13-14. The imagery of fine white linen on white horses doesn't sound like an army of angels being led by Jesus, but Christians. How did they get there? Finally, consider who is being judged and by what at the Great White Throne in Rev. 20:12. Do you want to be judged based on your works? I know I will come up really short.
I had the hardest time trying to figure out the end times until I realized the Tribulation is not for Christians. It's to bring the Jews to Jesus.
