According to Jacob 5, the Church is going to continue to need pruning by the servants right up until the end.
I can assist in that pruning if I stay in the vineyard and help wield a precise, careful scalpel - especially if those on my own tree aren't scared of the instrument I yield. I can't do it if I wield a machete wildly - or if I leave the vineyard altogether.
I'm not saying everyone has to stay and help in the pruning process. Only those who are willing to prune cautiously and with direction can do so properly. I'm just saying the Church needs help in that process from as many "servants" as possible. If someone can't do it now (or ever), I understand and am not going to condemn them. However, if someone can do it now (or at some point in the future), I'll join hands and share the task.
I'm going to do it regardless of how many others are helping (because it's my tree), but I'm going to be grateful for those who want to try to work with me - even if they are operating on different branches in different parts of the vineyard in different ways with different instruments.
