Do not think that a prayer must be heard by men to reach the ears of God. When pain grips your mind so tightly you cannot cry aloud, this very silence can be a loud entreaty. Remember Moses, so pressed in spirit, yet God said to him, "Wherefore criest thou unto me?" His voice was not heard, but his heart’s cry ascended. So too Hannah; her lips moved, but no sound came forth, and she obtained all she desired because her heart cried out. Even Abel, silent in death, spoke more powerfully than any trumpet through his blood. The prayer of the heart, when the mind is awake, needs no noisy tongue.
But do not trust in silence if the spirit sleeps. To think you need no other’s prayer, to say "What need have I of prayer?" is to be in the greatest danger. Even Paul welcomed the Church’s intercession. Yet neither can you rest solely on the prayers of saints while giving yourself to slumber. The wakeful soul has a twofold strength: its own earnest cry and the aid of holy supplication. If we rouse ourselves, we are heard; if we sleep, help from without profits nothing. God looks for your own zeal. If you contribute nothing, even what you seem to have may be taken away, for God deems the careless unworthy of His gifts. Strive to learn, and deep things are poured in; listen carelessly, and silence is the only righteous response.
Seek a place free from disturbance for such prayer. Jesus often resorted to a garden with His disciples, apart, to converse on necessary matters without distraction. The market place is a daily war, full of rocks and storms. Before you go out to it, make God propitious in quiet supplication. Prayer is your great weapon, not only at first light but in the watches of the night. A soul at peace within itself, having stilled its own warring passions, can live in godliness and honesty whatever outward tumults rage.
And know that when you pray, you do not inform an unwilling God or supply a lack in Him. He who made all things, visible and invisible, needs nothing. Yet He wills that you approach Him, not to change His mind, but to shape your own, that you may be made fit to receive what He already longs to give.
