Life's mission is to wake up and help others wake up, through sponsorship.
That requires sobriety and having 'a life' (home, occupation, and affairs).
These are the means of demonstration.
They are not the purpose.
The purpose is to serve God by helping others.
This kicks in the moment we have something to give, because we have received something.
To keep, give.
To get, give: turning on the tap draws down the water from the cistern.
Gravity (= principle = God) does all the work.
