Whenever a believer is in want, he should first inquire: Will such lack affect God? Does He want me to be in need? Or is it His Will to Supply my need?
When you see that God’s Will is to Supply your need, you can then ask Him to Fulfill His Will by Supplying what you need.
Having come to know His Will, you should now pray according to the Will of God which you know.
You pray that He will Fulfill His will.
The question is now no longer whether your need is met but whether God’s Will is Done.
