Everyone who asks something of God and does not receive it doubtless does not receive it for one of these reasons: either because they ask before the time, or they ask unworthily, or out of vainglory, or because if they received what they asked they would become proud or fall into negligence.
John ClimacusDo not stop praying as long as, by God's grace, the fire and the water have not been exhausted, for it may happen that never again in your whole life will you have such a chance to ask for the forgiveness for your sins.
John Climacus
