It's hard to rate this book. If I based it on my experience of the book, I would probably have to give it four stars. There were some sections/chapters that were hard to get through and which, after reading, I wasn't really sure what I had read. But there were lots of of sections/chapters that were convicting, challenging, encouraging and enlightening. I'll need to read this again, more slowly, to get its full worth. In short, I think the book deserves five stars and that giving it more time and effort would decrease the gap between its worth and what I got out of it.
From what I understood, I think this statement in one of the chapters toward the end really sums up the book: "As Christ will not quench the least spark kindled by himself, so will he damp the fairest blaze of goodly appearances which are not from above." In layman's terms I think the author's main points are that, in God's grace and mercy, he will preserve to the end the faintest measure of faith (because faith is not about quantity but quality, and any faith in God is of the finest quality) and God will win—he will have victory over the internal and external force that wage war against his rule and our hearts. The more I process these truths, the more I appreciate the author's focus. How encouraging to know that, as feeble as I am, God will carry me through to the end and that that end is complete and final victory.
Though there were some difficult sections, I loved many of the author's analogies/word pictures which were not only vivid but also very helpful. Some of my favorites are:
"The more sin is seen, the more it is hated, and therefore it is less. Dust particles are in a room before the sun shines, but they only appear then."
"Grace, as the seed in the parable, grows, we know not how. Yet at length, when God sees fittest, we shall see that all our endeavour has not been in vain. The tree falls upon the last stroke, yet all the strokes help the work forward."
"Thus the desperate madness of men is laid open, that they would rather be under the guidance of their own lusts, and in consequence of Satan himself, to their endless destruction, than put their feet into Christ's fetters and their necks under his yoke; though, indeed, Christ's service is the only true liberty. His yoke is an easy yoke, his burden but as the burden of wings to a bird which make her fly the higher."
"Christ performs his office in not quenching by stirring up suitable endeavors in us; and there are none more solicitous in the use of the means than those that are most certain of their good success. The reason is this: the means that God has set apart for the effecting of any thing are included in the purpose that he has to bring that thing to pass. And this is a principle taken for granted, even in civil matters; for who, if he knew before that it would be a fruitful year, would therefore hang up his plough and neglect tillage?"
"Where Christ establishes his government, he inspires care to keep the judgment clear and fresh, for while the judgment stands straight and firm, the whole frame of the soul continues strong and impregnable. True judgment in us advances Christ, and Christ will advance it. All sin is either from false principles, or ignorance, or thoughtlessness, or unbelief of what is true. By lack of consideration and weakness of assent, Eve lost her hold at first (Gen. 3:6). It is good, therefore, to store up true principles in our hearts, and to refresh them often, that, in virtue of them, our affections and actions may be more vigorous. When judgment is fortified, evil finds no entrance, but good things have a side within us to entertain them. While true convincing light continues, we will not do the least ill of sin for the greatest ill of punishment. `In vain the net is spread in the sight of any bird' (Prov. 1:17). While the soul is kept aloft, there is little danger of snares below. We must lose our high estimation of things before we can be drawn to any sin."
Other thoughts I found helpful are:
"We must acknowledge that in the covenant of grace God requires the truth of grace, not any certain measure; and a spark of fire is fire, as well as the whole element. Therefore we must look to grace in the spark as well as in the flame. All have not the like strong, though they have the like precious, faith (2 Pet. 1:1), whereby they lay hold of, and put on, the perfect righteousness of Christ. A weak hand may receive a rich jewel. A few grapes will show that the plant is a vine, and not a thorn. It is one thing to be deficient in grace, and another thing to lack grace altogether. God knows we have nothing of ourselves, therefore in the covenant of grace he requires no more than he gives, but gives what he requires, and accepts what he gives: 'If she be not able to bring a lamb, then she shall bring two turtle doves' (Lev. 12:8). What is the gospel itself but a merciful moderation, in which Christ's obedience is esteemed ours, and our sins laid upon him, wherein God, from being a judge, becomes our Father, pardoning our sins and accepting our obedience, though feeble and blemished? We are now brought to heaven under the covenant of grace by a way of love and mercy."
"It would be a good contest amongst Christians, one to labour to give no offence, and the other to labour to take none. The best men are severe to themselves, tender over others. Yet people should not tire and wear out the patience of others: nor should the weaker so far demand moderation from others as to rely upon their indulgence and so to rest in their own infirmities, with danger to their own souls and scandal to the church."
"But there is a difference between Christ and us in this case. Because Satan had nothing of his own in Christ his suggestions left no impression at all in his holy nature, but, as sparks falling into the sea, were presently quenched. Satan’s temptations of Christ were only suggestions on Satan’s part, and apprehensions of the vileness of them on Christ’s part. To apprehend ill suggested by another is not ill. It was Christ’s grievance, but Satan’s sin. But thus he yielded himself to be tempted, that he might both pity us in our conflicts, and train us up to manage our spiritual weapons as he did. Christ could have overcome him by power, but he did it by argument."
"It should encourage us to duty that Christ will not quench the smoking flax, but blow on it till it flames. Some are loath to do good because they feel their hearts rebelling, and duties turn out badly. We should not avoid good actions because of the infirmities attending them. Christ looks more at the good in them which he means to cherish than the ill in them which he means to abolish. Though eating increases a disease, a sick man will still eat, so that nature may gain strength against the disease. So, though sin cleaves to what we do, yet let us do it, since we have to deal with so good a Lord, and the more strife we meet with, the more acceptance we shall have. Christ loves to taste of the good fruits that come from us, even though they will always savor of our old nature."
"A Christian complains he cannot pray. `Oh, I am troubled with so many distracting thoughts, and never more than now!' But has he put into your heart a desire to pray? Then he will hear the desires of his own Spirit in you. `We know not what we should pray for as we ought' (nor how to do anything else as we ought), but the Spirit helps our infirmities with `groanings which cannot be uttered' (Rom. 8:26), which are not hid from God. `My groaning is not hid from thee' (Psa. 38:9). God can pick sense out of a confused prayer. These desires cry louder in his ears than your sins."
"Hence it is that we are saved by the grace of faith which carries us out of ourselves to rely upon another; and faith works best alone, when it has least outward support. Hence is is that we often fail in lesser conflicts and stand firm in greater, because in the lesser we rest more in ourselves, in the greater we fly to the rock of our salvation, which is higher than we (Psa. 61:2)."
"Oh, what a confusion is this to Satan, that he should labour to blow out a poor spark and yet should not be able to quench it; that a grain of mustard seed should be stronger than the gates of hell; that it should be able to remove mountains of oppositions and temptations case up by Satan and our rebellious hearts between God and us. Abimelech could not endure that it should be said, 'A woman slew him' (Judg. 9:54); and it must needs be a torment to Satan that a weak child, a woman, a decrepit old man should, by a spirit of faith, put him to flight."
"Grace conquers us first, and we, by it, conquer all else; whether corruptions within us, or temptations from outside us."
"And because knowledge and affection mutually help one another, it is good to keep up our affections of love and delight by all sweet inducements and divine encouragements; for what the heart likes best, the mind studies most. Those that can bring their hearts to delight in Christ know most of his ways. Wisdom loves him that loves her. Love is the best entertainer of truth; and when it is not entertained in the love of it (2 Thess. 2:10), lovely as it is, it leaves the heart, and will stay no longer. It has been a successful way of corrupting the judgment, to begin by withdrawing love, because, as we love, so we tend to judge. And therefore it is hard to be affectionate and wise in earthly things. But in heavenly things, where there has been a right informing of the judgment before, the more our affections grow, the better and clearer our judgments will be, because our affections, though strong, can never rise high enough to reach the excellency of the things. We see in the martyrs, when the sweet doctrine of Christ had once gained their hearts, it could not be removed again by all the torments the wit of cruelty could devise. If Christ has once possessed the affections, there is no dispossessing of him again. A fire in the heart overcomes all fires without."
"Of all persons, a man guided by Christ is the best; and of all creatures in the world, a man guided merely by will and affection, next to the devil, is the worst. The happiness of weaker things stands in being ruled by stronger. It is best for a blind man to be guided by him that has sight. It is best for sheep, and other feckless creatures, to be guided by man. And it is happiest for man to be guided by Christ, because his government is so victorious that it frees us from the fear and danger of our greatest enemies, and tends to bring us to the greatest happiness that our nature is capable of. This should make us rejoice when Christ reigns in us. When Solomon was crowned, the people rejoiced so that the city rang (1 Kings 1:45). Much more should we rejoice in Christ our king. And likewise for those whose souls are dear to us, our endeavor should be that Christ may reign in them also, that they may be baptized by Christ with this fire (Matt. 3:11), that these sparks may be kindled in them. Men labour to cherish the spirit and mettle, as they term it, of those they train up, because they think they will have use of it in the manifold affairs and troubles of this life. Oh, but let us cherish the sparks of grace in them; for a natural spirit in great troubles will fail, but these sparks will make them conquerors over the greatest evils."
"But if we have this for a foundation truth, that there is more mercy in Christ than sin in us, there can be no danger in thorough dealing. It is better to go bruised to heaven than sound to hell. Therefore let us not take off ourselves too soon, nor pull off the plaster before the cure be wrought, but keep ourselves under this work till sin be the sourest, and Christ the sweetest, of all things. And when God's hand is upon us in any way, it is good to divert our sorrow for other things to the root of all, which is sin. Let our grief run most in that channel, that as sin bred grief, so grief may consume sin."
As I look back through my favorite sections of this book, I appreciate it more and am assured that re-reading it would glean even more valuable insights. You can find this book online for free from a variety of sources and it is fairly short (about 130 pages in my paperback version). Lots of good stuff here and worth the effort.
