The Privy Key of Heaven
(A Discourse of Closet Prayer)
by Thomas Brooks, published during 
the awful plague of London in 1665.
    "But when you pray, go into your room, close
    the door and pray to your Father, who is unseen.
    Then your Father, who sees what is done in
    secret, will reward you." Matthew 6:6
    
    EPISTLE DEDICATORY
 
    Beloved in Our Dear Lord Jesus,
    The Lord at several times, and in several ways, has exercised you all in the 
    furnace of affliction. This book may reach you all, and speak to you 
    all—when I can not, or when I may not, or which is more, when 
    I am not.
    Dear friends, many and great have been the breaches that 
    the Lord has made upon your persons, upon your near and dear relations, and 
    upon your sweetest comforts and contentments. There is not one of you but 
    may truly say with Job, "He breaks me with breach upon breach," Job 16:14. 
    God has chastised you all round with various rods; and oh that the Lord 
    would help you all to "hear the rod, and him who has appointed it," Micah 
    6:9.
    Now that you may give me leave a little to open and apply 
    to your particulars, that
    "The Lord's voice cries unto the city, and the man of 
    wisdom shall hear your name: hear the rod, and him who has appointed it."
    Micah 6:9 
    The matter that I shall offer to your consideration from 
    this scripture, will be not only of special concernment to yourselves, but 
    also of high concernment to all sorts and ranks of men and women, in this 
    sad day, when the sword devours on the one hand, and the pestilence rages on 
    the other hand.
    
    "The Lord's voice cries unto the city." Tremellius 
    turns it thus, "The voice of the Lord does preach unto this city, for what 
    the matter is, you see: hear you the rod," etc. This city, namely, 
    Jerusalem, and so consequently to all the Israelites; for in this city all 
    offices and duties of godliness and humanity were more religiously 
    performed, or to be performed, than in any other place, because of the 
    presence and majesty of God that was among them. "But your Majesty sees what 
    wickedness is practiced among them," as is evident in the verses following.
    
    "Cries." The word is from kara, which 
    signifies,
    First, "To cry aloud," or "to make a noise," Isa 58:1; 
    "cry aloud" there is kara. The word signifies, to cry so loud as that all 
    may hear that have ears to hear.
    Secondly, The word signifies, "openly to proclaim, 
    preach, or publish a thing." Exod 33:19, "I will proclaim the name of the 
    Lord before you." Here is the word kara.
    Thirdly, The word signifies, "to cry out." Gen 39:15, "I 
    lifted up my voice and cried." Here is kara.
    
    "And the man of wisdom shall see your name." 
    Vethushiia properly signifies essence; and, therefore, according to the 
    Hebrew, the words should be read thus, "And the man of essence shall see 
    your name," etc., that is, he who is a man indeed, he who is not a sot, a 
    stock, a stone. Most men are men of folly, and so not worthy of the name of 
    men; but as for such as are truly wise, they "shall see your name." There 
    is a great measure of spiritual art, of holy and heavenly wisdom required, 
    both to enable a man to hear the voice of the rod and to understand the 
    language of the rod. This wisdom is too high for a fool, Prov 24:7.
    
    "Shall see your name." Now the Hebrew word here used, 
    signifies to fear; and so the words will run smoothly thus, "The man of 
    wisdom, or of essence, shall fear your name," considering that, it is 
    majesty itself that cries, and that he is immediately to deal with God 
    himself, and not with a poor, weak, mortal worm.
    
    "Hear the rod." The word hear signifies,
    First, "To mark, observe, and attend to what is said." 
    Gen 29:33, "The Lord has heard that I was hated;" that is, "he has marked 
    it, he has observed it." So here, Oh mark the rod! Oh observe the rod! Oh 
    attend to what is spoken by the rod!
    Secondly, The word signifies, "to understand what is 
    spoken;" so Gen 42:23, "They knew not that Joseph understood them." In the 
    Hebrew it is, "that Joseph heard them." Now to hear the rod, is to 
    understand what is spoken to us by the rod.
    Thirdly, The word signifies, "to believe a thing reported 
    to be true;" so Exod 6:9, "They hearkened not unto Moses," that is, "they 
    did not believe the report that Moses made." "Hear the rod," that is, 
    "believe the report the rod makes." The rod reports, that of all evils sin 
    is the greatest evil; and that of all bitters, sin is the greatest bitter. 
    Oh believe the report of the rod! The rod reports, that God is angry, that 
    God is displeased. Oh believe its report! The rod reports the creatures to 
    be mere vanity and vexation of spirit. Oh believe its report! The rod 
    reports our nearest and dearest comforts, contentments, and enjoyments to be 
    mixed, mutable, and momentary. Oh believe its report! The rod reports sin to 
    be vile, and the world to be vain, and heaven to be glorious, and Christ to 
    be most precious. Oh believe its report!
    
    "The rod." The Hebrew word matte, that is here 
    rendered rod, has three significations:
    First, It denotes "power and strength:" Psalm 2:9, "a rod 
    of iron."
    Secondly, It denotes "rigid and harsh government:" Isa 
    14:5, "The Lord has broken the staff," or rod, "of the wicked;" that is, 
    "their rigorous and cruel government." Nebuchadnezzar had sorely afflicted 
    the children of Judah; he was a rod, that broke them in pieces, and ruled 
    over them with much rigor in Babylon.
    Thirdly, It denotes "sore afflictions and heavy 
    judgments:" Psalm 89:32, "I will visit your transgressions with a rod." And 
    thus you are to understand the word rod in the text.
    
    "And him who has appointed it." It is God who 
    appoints the rod, and ordains it for the revenge of the quarrel of his 
    covenant. The Hebrew word signifies properly "to appoint" or "constitute." 
    It is God who appoints the rod, and who constitutes it to do what service he 
    pleases. It is God who has not only a permissive—but also an active, hand, 
    in all the afflictions that come upon his people.
    And let thus much suffice for the opening of the words.
    Now, though this choice garden affords many sweet 
    flowers—yet I shall only present you with one, which is this, namely,
    That all the afflictions, troubles, and trials which 
    God lays upon His people, are his rod. It is their highest and greatest 
    concernment to hear the voice of the rod, and to learn those lessons that 
    God would have them learn by the rod.
    
    For the opening and clearing up of this important point, 
    I shall endeavor these two things:
    First, To show you in what respects afflictions are like 
    unto a rod.
    Secondly, To show you what those special lessons are, 
    that you are to learn by the rod.
    Dear friends, 
    The following discourse on closet prayer I heartily recommend to your 
    serious perusal. I have many reasons to hope, that when you have once read 
    it over, you will be more in love with closet prayer than ever, and that you 
    will set a higher price upon closet prayer than ever, and that you will make 
    a better and fuller improvement of closet prayer than ever yet you have 
    done. Consider what I say in my epistle to the reader, and labor so to 
    manage this little treatise, which now I put into your hands, that God may 
    be glorified, your own souls edified, comforted, and encouraged in the ways 
    of the Lord, and that you may be "my crown and joy, in the great day of our 
    Lord Jesus," 1 Thes. 2:19-20.  
    Christian Reader—The epistle dedicatory being so large, I shall do little 
    more than give you the grounds and reasons of sending forth this little 
    piece into the world, especially in such a day as this is. Now, my 
    reasons are these:
    1. First, Because God by his present dispensations calls more loudly for 
    closet prayer now, than he has done in those last twenty years that are now 
    passed over our heads. See more of this in the 16th argument for closet 
    prayer.
    2. Secondly, Because I have several reasons to fear that many Christians 
    do not clearly nor fully understand the necessity, excellency, and 
    usefulness of this subject, and that many, oh that I could not say any, live 
    in too great a neglect of this indispensable duty; and that more than a few, 
    for lack of light, err in the very practice of it.
    3. Thirdly, For the refreshing, support, and encouragement of all those 
    churches of Christ that walk in the fear of the Lord, and in the comforts of 
    the Holy Spirit, etc., especially that particular church to whom I stand 
    related.
    4. Fourthly, To preserve and keep up the power of religion and godliness 
    both in men's houses, hearts, and lives. The power of religion and godliness 
    lives, thrives, or dies, as closet prayer lives, thrives, or dies. Godliness 
    never rises to a higher pitch than when men keep closest to their closets, 
    etc.
    5. Fifthly, Because closet prayer is a most sovereign remedy, a most 
    precious antidote of God's own prescribing, against the plague that now 
    rages in the midst of us, 1 Kings 8:37-39, etc.
    6. Sixthly, Because every man is that really which he is secretly. 
    Never tell me, how handsomely, how neatly, how bravely, this or that man 
    acts his part before others; but tell me, if you can, how he acts his part 
    before God in his closet; for the man is that certainly, which he is 
    secretly. There are many who sweat upon the stage that are cold in their 
    closets.
    7. Seventhly, Though many worthies have done worthily upon all other 
    parts of prayer—yet there are none either of a former or later date, that 
    have fallen under my eye, who have written any treatise on this subject. I 
    have not a little wondered that so many eminent writers should pass over 
    this great and princely duty of closet-prayer, either with a few brief 
    touches, or else in a very great silence. If several Bodies of Divinity are 
    consulted, you will find that all they say clearly and distinctly as to 
    closet-prayer, may be brought into a very narrow compass, if not into a 
    nutshell. I have also inquired of several old disciples, whether among all 
    the thousand sermons that they have heard in their days, that ever 
    they have heard one sermon on closet-prayer? and they have answered, No. I 
    have also inquired of them, whether ever they had read any treatise 
    on that subject? and they have answered, No. And truly this has been no 
    small encouragement to me, to make an offer of my mite; and if this small 
    attempt of mine shall be so blessed, as to provoke others who have better 
    heads, and hearts, and hands, than any I have, to do Christ and his people 
    more service, in the handling of this choice point in a more copious way 
    than what I have been able to reach unto, I shall therein rejoice.
    8. Eighthly, and lastly, That favor, that good acceptance and fair 
    quarter that my other poor labors have found, not only in this nation—but in 
    other countries also, has put me upon putting pen to paper once more; and I 
    hope that the good will of him who "dwelt in the bush," will rest upon this, 
    as it has to the glory of free grace rested upon my former endeavors. I 
    could add other reasons—but let these suffice.
    Good reader, when you are in your closet, pray hard for a poor, weak, 
    worthless worm, that I may be found faithful and fruitful to the death, that 
    so at last I may receive a crown of life. So wishing you all happiness both 
    in this lower and in that upper world, I rest,
    Yours in our dear Lord Jesus,
    Thomas Brooks.
