I read this too with interest but it's not as exciting as I first hoped.
what it says is that the destruction of religion will not mean the destruction of all members, that some will leave the religions. Then it says:
“Similarly, we cannot expect that the future interruption in the great tribulation will result in an influx of new believers. Rather, it will be an opportunity for all true believers to prove their love for Jehovah and give their support to Christ’s brothers.
“No doubt God’s people will proclaim a hard-hitting judgment message. This may well involve a declaration announcing that Satan’s wicked world is about to come to its complete”
So basically they are saying, religion would be destroyed, some members will survive and renounce those religions, then the Jw message would get harder, but we shouldn't expect mass conversion, the key to survival is not being a good person, believing in Christ and being a sincere Christian but as usual is 'supporting Christs 'brothers''
remember though this only matters if they're actually right about any of these predictions and an honest look at the last 120 years would say they're probably not!
