To him who believes, all things are possible and to him who believes
not, nothing is possible.
To him who believes that God is real, God will be real and will
reveal Himself to him.
To him who does not believe that God exists; God will hide Himself
from him and it will appear to him that God doesn't exist.
Jesus said, As thou hast believed, so be it done to thee. (Matthew
5:13)
Brethren, it is not God who is withholding from you; it is you by
your own lack of believing that causes the things of Heaven's Glory
to be withheld from you.
You receive not because you ask not and you ask not because you do
not believe.
If you truly believed that God would answer your prayer you would
ask.
