So which form, formal or spontaneous, do you all prefer?
Or maybe rather, what do you like about each of the two forms?
While the church I most subscribe to has prayers....they often speak in a language for the conventional Christian and aren't for me.
We do open and close service with generic prayers but that is not what I think you were asking.
I think/believe you are asking regarding prayers for change, to alter some existing situation (weather, health, wealth, success etc)
If my assumption is wrong oh well I am blazing ahead with my answer.
Now that I said that in my head my answer was reformatted from a spontaneous uttering to the root of my thought which is simpler and more straightforward.
The Serenity Prayer is an invocation by the petitioner for wisdom to understand the difference between circumstances ("things") that can and cannot be changed, asking courage to take action in the case of the former, and serenity to accept in the case of the latter.
There are dozens of interpretations, many of them overly religious or invoking entities which I don't believe in....but there is also Mother Goose...
For every ailment under the sun
There is a remedy, or there is none;
If there be one, try to find it;
If there be none, never mind it.
For clarification, I don't pray to any.heavemly spirit to phydical.conditions on earth. I pray (focus) on either changing my perspective on a situation or my acceptance of reality or encourage myself to have the courage and wherewithal to physically do something about it.
