While it is true that we are to pray according to God's will, it is also true that we have a free will, and most of the time our Prayers are for trouble to be relieved, or for healing to manifest.
So, it is always God's will to help His Children.
Praying according to God's Will, is to understand that God's ear is our hope, and God's help is our security.
Are you a parent, yet?
If not and you become one, you will find that Children have their own will, and Christians who are the Children of God, have their own will.
God's Will for the born again, would be for our wisdom to be increased, our health to be maintained, and for our discipleship to be perfected.
Some have this idea that God wants you broke and sick. This is the heretic's "poverty Gospel", and they will tell you that you are made more spiritual if you are sick and broke.
I'll tell you that you will be made more bitter, and bitter does not make you better.
There can be a "vow of poverty", and you can make yourself a "eunuch", but, that is similar to a Ministry Call, and there is a sanctification for that, which is not the usual.
