Answer: Everyone must be like Moses. It isn’t enough to be a passive member because by that you drill a hole in the general boat. You have to do your best, otherwise you are not a friend.
Imagine that we are all hanging from a cliff above an abyss, each holding the other, and you are holding everyone with a quarter of your strength. How can you be called a friend then? You have to give 100% of your powers every moment as much as you possibly can. Of you will not be able to do it, and you will quit time and time again and then come back. But in order to clarify things as quickly as possible, you have to understand that things can be that way.
Of course the desired and reality are not always consistent with each other. But still, you have to check yourself with regard to the ideal state. Only then can you really be called a friend.
Our connection creates a place for the revelation of the Creator, and it’s only for that reason that we give it priority. By connecting we create the conditions for the revelation of the Creator.
