I think I understand what you're saying here, and the quote from St. Paul is excellent.
On the other hand, Jesus Himself taught us to pray for our daily bread as well as all of our other needs, to pray as children do their Father (and anything children can innocently want, they can innocently ask their Father for).
I know I, myself, wuld do well to learn to serenely ask for God's will to be done, and leave it at that without further perturbation. But is it our nature, even at our best, to be so unperturbed? Jesus Himself wept when He heard of Lazarus' death; He suffered anxiety and anguish in the Garden, and not without struggle did He finally pray "Not my will, but Thine be done."
If I may ask, please pray for me and I will for you.
How about this?
I Thank and Praise you Heavenly Father for the work you are doing in Mrs. Don-o's life In Jesus Name I pray Amen. :)
