To the extent that our souls are empty of faith, they are filled with fear. We read of people who have died by no other cause than their fear. But we never read of anyone, once brought to life by faith, dying because of fear.Triumphing over Sinful Fear, 35
Our immoderate love of life and its comforts and conveniences is another cause of sinful fear in times of danger. If we loved our lives less, we would fear and tremble less.Triumphing over Sinful Fear, 42
Do you mortify; do you make it your daily work; be always at it whilst you live; cease not a day from this work; be killing sin or it will be killing you.Of the Mortification of Sin in Believers Chapter 2
Upon their king's death, it was the Persians' custom (I am not saying it was laudable) to grant everyone liberty for five days to do whatever they wanted. The unbridled lust was so great that it made the people long and pray for the installment of their next king. In this way it endeared government to them. Blessed be God for law and government, for using them to curb people's raging lusts, and thereby procuring rest and comfort for us in the world!Triumphing over Sinful Fear, 22-23
That is why the unregenerate person cannot understand the urgency of the gospel message: until they see the depth of their sin and the holiness of God, they find no reason to seek remedy for their condition.
When I turn to the map of the world I must say the same thing. It matters not what quarter I examine: I find men's hearts are everywhere the same, and everywhere wicked. Sin is the family disease of all the children of Adam.Old Paths, Ch 7
You can never part with sin soon enough; it is a cursed inmate, that will surely bring mischief upon the soul that harbours it. It will set its own dwelling on fire.Works 7:147
a trembling life destroys the spiritual comforts that flow from God's promises. It also destroys our experience of the promises - the sweetest pleasures we have in this world.
If we fear God, we dare not ignore what He commands. If His fear is exalted in our hearts, it will enable us to obey Him in duties accompanied with deep self-denial.Triumphing over Sinful Fear, 20
At the heart of all sin is a lie. The lie says to all of us in our sin, "The act you are now doing, the desire or attitude you are now feeling is not very bad because there are much worse things, not very bad because everyone else experiences the same things, not very bad because you can't help it, not very bad because there is no God, or, if that won't work, God knows you are but frail and weak and he will tolerate and pity your sin." There are a thousand distortions of the truth which sin brings with it into the human heart, so that Jeremiah cries out, "The heart is deceitful above all things and desperately corrupt; who can understand it?" (17:9).
Look to it, my dear friends, that none of you be found Christless at your appearance before him. Those that continue Christless now, will be left speechless then. God forbid that you that have heard so much of Christ, and you that have professed so much of Christ, should at last fall into a worse condition than those that never heard the name of Christ.
Providence is wiser than you, and you may be confident it has suited all things better to your eternal good than you could do had you been left to your own option.
Sin may be comprehensively defined as lack of conformity to the law of God in act, habit, attitude, outlook, disposition, motivation, and mode of existence.Concise Theology, Section 31
A young ungrounded Christian, when he sees all the fundamental truths, and sees good evidence and reasons of them, perhaps may be yet ignorant of the right order and place of every truth. It is a rare thing to have young professors to understand the necessary truths methodically: and this is a very great defect: for a great part of the usefulness and excellency of particular truths consisteth in the respect they have to one another. This therefore will be a very considerable part of your confirmation, and growth in your understandings, to see the body of the Christian doctrine, as it were, at one view, as the several parts of it are united in one perfect frame; and to know what aspect one point has upon another, and which are their due places. There is a great difference betwixt the sight of the several parts of a clock or watch, as they are disjointed and scattered abroad, and the seeing of them conjointed, and in use and motion. To see here a pin and there a wheel, and not know how to set them all together, nor ever see them in their due places, will give but little satisfaction. It is the frame and design of holy doctrine that must be known, and every part should be discerned as it has its particular use to that design, and as it is connected with the other parts.
