Don't hear too much talk about the role of the Two Witnesses. No doubt they will thwart antichrist for the duration of their ministry. With the great power entrusted unto them they will be able to counter every move the AC makes. I assume a great part of their ministry will be protecting the saints to the full extent of their power. Does the AC assault on the saints take off after the Witnesses are slain? We may not have long to find out.
