There is a mercy in this, that the God of heaven hears the prayer which never reaches a human ear. Like Nehemiah before the king, you have offered a brief, silent prayer within yourself, in the innermost shrine of the soul, in the Holy of Holies of your own secret heart, and such prayer, though it be as the blinking of an eye, prevails with God. He does not need loud words or outward signs, for He reads the heart, and wordless prayers are heard in heaven.
Be encouraged that you may speak with the Lord many times in a day in this fashion, on the spot, without withdrawing to your chamber, and He will hear. The Spirit of grace must first give the prayer before we can pray aright, and when He puts the cry into the heart, it lies there ready for use. See to it then that your heart goes with your prayer, and not merely your lips. The most mighty prayer is that which cannot be timed or regulated, but which comes because the suppliant must pray, even if it be only, Oh God, hear me.
Remember also that God has spoken in His holiness, and His Word is fixed certainty and pure truth. When you pray, you have power to plead, Do as Thou hast said. It is written is a sword to flash in the face of every foe, and to carry into the presence of God. He has revealed Himself in Scripture as Jehovah, the God who made heaven and earth, the same God of Sinai and of Calvary, and grace enables the renewed heart to appropriate Him and to say, My God, my God. If you are His child through faith in the Lord Jesus Christ, then you are an heir of God, and all that God has and all that God is belongs to you, for Christ has said, My Father and your Father, My God and your God. There is no other way of salvation, for salvation is through Jesus Christ alone.
May the Lord who hears silent prayers grant you quiet and unshaken assurance as you call upon Him in the day of trouble, for to call upon Him sincerely is to honor Him, and He has promised, I will deliver you. May He lead you to know Him truly, for to know Him is to love Him, and to love Him is to give Him your heart. My son, give me thine heart, He says, and blessed are those who answer freely, today, while it is called today. May He search your heart, form the prayer there according to His will, and answer you for His glory and your good, making His mercy great unto the heavens over you, and exalting His name above all.
