I doubt it. At least, not for a long time. Even if they wanted to push the idea that JWs must return to door to door work the push back from the public could be tremendous.
I would not like it if they were knocking on the doors of elderly people.
We are going to have to show proof of vaccination here in Australia in order to enter into many establishments, including hospitals, old age homes, public gatherings and other places.
Since their will be these restrictions in place, it doesn't seem right that you could have people entering people's private properties without their prior approval. If JWs started doing this, the issue would have to be legally addressed. This would bring unwarranted attention to them and I don't think they would want this negative publicity even though they fought for it in the courts years ago. Now they would be fighting public opinion. Are they willing to withstand this persecution, fighting the fine fight for the faith?
