This is the time where we get close to the end of the church year, and that certainly changes our perspective. We tend to plan as though things will continue to be as they are for a while. But that is certainly not the case.
Today people think that the early Christians all thought that Jesus was coming back quite soon. And while that certainly was a thought among some early Christians, it wasn't what everyone was thinking.
Jesus' perspective in the Gospel according to Luke is slightly different than the rest, and in that account Jesus says that the end would not come immediately.
That certainly fits with the progression and advancement that comes with the book of Acts. The disciples didn't just sit in Jerusalem and wait for Jesus to come back.
All the things that Jesus has mentioned about the sun being darkened, all those things have already happened. And so the end could happen literally any day.
It could be today, and that's a good reminder.
We're not in charge. And that's a good thing.
