Jesus arrival was anticipated for a very long time.
He was to be the final "Lamb" to be sacrificed.
Animal sacrifice was a constant feature of worship for a couple thousand years.
It was the heart and core of that worship.
Jesus' death removed the need for that constant feature.
Do you really think that Daniel would refer to the door-to-door preaching work that wouldn't take place for a couple thousand years after he wrote that, and would only last a few decades, as a "constant feature"?
The "preaching work" is a tiny blip in all of human history's worship if Jehovah.
I don't think it qualifies as a "constant" feature.
Do you think it does?
