Keeping the Heart
by John Flavel
"Keep your heart with all diligence; 
for out of it are the issues of life."
Proverbs 4:23
    
    
    I now proceed to improve and APPLY the subject
    
    You have seen that the keeping of the heart is the great 
    work of a Christian, in which the very soul and life of true religion 
    consists, and without which all other duties are of no value in the sight of 
    God. Hence, to their consternation, I give a 
    special warning to hypocrites and formal professors—that the pains and 
    labors which they have undergone in religion are of no value, and will turn 
    to no good account. Many splendid religious services have been 
    performed by men, which God will utterly reject! They will not stand on 
    record in order to an eternal acceptance, because the performers took no 
    heed to keep their hearts with God. This is that fatal rock on which 
    thousands of vain professors dash and ruin themselves eternally! They are 
    exact about the externals of religion—but heedless of their 
    hearts! O how many hours have some professors spent in hearing, praying, 
    reading and conferring! And yet, as to the main end of piety, they might as 
    well have sat still and done nothing—as the great work, I mean heart-work, 
    was all the while neglected. Tell me, vain professor, when did you shed a 
    tear for the deadness, hardness, unbelief or earthliness of your heart? And 
    do you think your easy, heartless religion can save you? If so, you must 
    invert Christ's words, and say, "Wide is the gate and broad is 
    the way that leads to life, and many there are who enter." Hear me, 
    you self-deluding hypocrite; you who have put off God with heartless 
    duties—you who have acted as if you had been worshiping an idol! You who 
    could not search your heart, and regulate it, and exercise it in your 
    performances; how will you abide the coming of the Lord? how will you hold 
    up your head before him, when he shall say. "O you shamming, false-hearted 
    man! How could you profess to worship me—without your heart? With what face 
    could you so often tell me that you loved me, when you knew in your 
    conscience that your heart was not with me?" O tremble to think what a 
    fearful judgment it is to be given over to a heedless and careless heart, 
    and then to have mere religious duties, instead of a rattle, to quiet 
    and still the conscience!
    
    I infer for their humiliation, that unless the people of 
    God spend more time and pains about their hearts than they ordinarily 
    do—they are never likely to do God much service, or to possess much comfort 
    in this world. 
I may say of that Christian who is remiss and 
    careless in keeping his heart, as Jacob said of Reuben, "you shall not 
    excel." It grieves me to see how many Christians there are who live at a 
    poor, low rate—both of service and comfort, and who go up and down dejected 
    and complaining. But how can they expect it should be otherwise, while they 
    live so carelessly? O how little of their time is spent in the closet, in 
    searching, humbling, and quickening their hearts!
    Christian, you say your heart is dead, and do you wonder 
    that it is, so long as you do not nourish it with the fountain of life? If 
    your body had been as starved as your soul has—that would have been dead 
    too. And you may never expect that your heart will be in a better 
    state—until you take more pains with it.
    O Christians! I fear your zeal and strength have run in 
    the wrong chapel; I fear that most of us may take up the Church's complaint: 
    "They have made me the keeper of the vineyards—but my own vineyard have I 
    not kept!" Two things have eaten up the time and strength of the professors 
    of this generation, and sadly diverted them from heart-work.
    First. Fruitless controversies, 
    started by Satan, have greatly increased 
    the neglect of our hearts. Satan's purpose in fruitless 
    controversies, is to take us off from practical godliness, and to make us 
    puzzle our heads—when we should be inspecting our hearts. How little have we 
    regarded the observation: "It is a good thing that the heart be established 
    with grace, and not with meats," (that is, with disputes and controversies 
    about meats,) "which have not profited those who have been occupied 
    therein." How much better it is to see men live exactly—than to hear them 
    dispute with subtlety! These unfruitful questions, how have they rent 
    the churches, wasted time and energy, and taken Christians off from their 
    main business! Would it not have been better if the questions agitated among 
    the people of God of late had been such as these: "How shall a man 
    distinguish the special from the common operations of the Spirit? How may a 
    soul discern its first backslidings from God? How may a backsliding 
    Christian recover his first love? How may the heart be preserved from 
    unseasonable thoughts in duty? How may a bosom-sin be discovered and 
    mortified?" etc. Would not this course have tended more to the honor of true 
    religion and the comfort of souls? I am ashamed that the professors of this 
    generation are yet insensible of their folly. O that God would turn their 
    disputes and contentions, into practical godliness!
    
    Second. Worldly cares and 
    encumbrances have greatly increased the neglect of our hearts. 
    The heads and hearts of multitudes have been filled with such a crowd and 
    noise of worldly business, that they have lamentably declined in their zeal, 
    their love, their delight in God, and their heavenly, serious, and 
    profitable way of conversing with men. How miserably have we entangled 
    ourselves in this wilderness of trifles! Our discourses, our conferences, 
    no, our very prayers are tinged with it! We have had so much to do without, 
    that we have been able to do but little within. And how many precious 
    opportunities have we thus lost? How many admonitions of the Spirit have 
    passed over unfruitfully? How often has the Lord called to us, when our 
    worldly thoughts have prevented us from hearing? But there certainly is a 
    way to enjoy God even in our worldly employments. If we lose our views of 
    him when engaged in our temporal affairs, the fault is our owns Alas! that 
    Christians should stand at the door of eternity, having more soul-work upon 
    their hands than their time is sufficient for—and yet be filling their heads 
    and hearts with trifles!
    
    I infer, lastly, for the awakening of all, that if the 
    keeping of the heart be the great work of a Christian, then there are but 
    few real Christians in the world.
 If everyone who has learned the 
    dialect of Christianity, and who can talk like a saint; if everyone who has 
    gifts and abilities, and who can preach, pray, or discourse like a 
    Christian; in a word, if all such as associate with the people of God and 
    partake of ordinances may pass for Christians—then indeed the number is 
    great! But alas! how few can he found, if you judge them by this rule—how 
    few are there who conscientiously keep their hearts, watch their 
    thoughts and look scrupulously to their motives! Indeed there are 
    few closet-men among professors. It is easier for men to be 
    reconciled to any other duties in religion than to these. The profane part 
    of the world will not so much as meddle with the outside of any pious 
    duties, and least of all with these; and as to the hypocrite, though he may 
    be very particular in externals—you can never persuade him to undertake this 
    inward, this difficult work; this work, to which there is no inducement from 
    human applause; this work, which would quickly unveil what the hypocrite 
    cares not to know. So that by general consent, this heart-work is only done 
    by a few pious ones—and I tremble to think how few!
    If the keeping of the heart be so important a business; 
    if such great advantages result from it; if so many valuable interests are 
    wrapped up in it—then let me call upon the people of God everywhere to 
    engage heartily in this work! O study your hearts, watch your hearts, keep 
    your hearts! Away with fruitless controversies and all idle questions; away 
    with empty names and vain shows; away with unprofitable discourse and bold 
    censures of others—and turn in upon yourselves! O that this day, this hour, 
    you would resolve upon doing so!
    Reader, methinks I shall prevail with you. All that I beg 
    for is this, that you would step aside oftener to talk with God and your own 
    heart; that you would not allow every trifle to divert you; that you would 
    keep a more true and faithful account of your thoughts and affections; that 
    you would seriously demand of your own heart at least every evening—'O my 
    heart, where have you been today, and what has engaged your thoughts?'
