Why we don’t believe Book of Revelation was completed in Ad 70?

For this to be true revelation needed to be written before ad 70 . However we can act out of time as a spirit being and sit alongside father to do the acts He does so in some sense this question may be irrelevant . It has caused a lot of controversy.

This is a good article showing why we don’t believe this was the case . But do ask Father . Nothing is resonating with me about this doctrine and it has massive implications on our role in end times .
