We will look closely at each of the passages involved in end time discussions.
My answers will be centered around what I think you are getting at, as you are asking very broad questions.
What is taught in Mt.24?
Signs of the end of the age and Jesus' return, including birth pangs, and things that come after.
What is taught in Luke 21?
Signs of the end of the age and Jesus' return, including birth pangs, and things that come before.
What about Rev.20?
What happens after this age, and the age to come.
Has the kingdom started or is it yet future?
Which kingdom?
Does Jesus have to be on the physical earth, on a physical throne?
Have to be? Does God "have to" do anything? But what did Jesus say?
Is there a rebuilt temple?
Or do you mean, will there be? Who is the man of sin?
Is Jerusalem the Holy City?
Jerusalem, Jerusalem, Lift up your voice and SING! Hosanna in the highest! Hosanna to your King!
What is Dan.9:24-27 about?
God's plan for Israel.
When is the rapture?
Pre-trib.
What happened in 70A.D.?
When you see Jerusalem surrounded by armies, know that it's destruction is near.
What has been fulfilled?
Lots?
What is left to fulfill?
The rest of the birth pangs, then the end of the age / 70th week of Daniel, then Jesus returns, gathers Israel, takes His throne, judges the nations, and the promised Kingdom begins, for 1000 years, then Man is judged, and a new creation begins.
Much love!
