Didymus the Blind
Patristic
c. A.D. 313–398
“The Savior said: "Ask and you will receive. Everyone who asks will receive." How can it be then that some people pray but do not get what they ask for? To this it must be answered that if someone comes to prayer in the right way, omitting none of the prerequisites for intercession, he will receive everything he asks for. But if someone appears to be going beyond the permissible bounds laid down for intercession, he will appear to be asking for something in the wrong way and therefore will not obtain it.”
