“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.”
“If the death of Christ was that which satisfied God for our sins, there is infinite evil in sin, since it could be not expiated but by an infinite satisfaction. Fools make a mock at sin, and there are few in the world who are duly sensible of its evil; but certainly, if God should exact of thee the full penalty, thy eternal sufferings could not satisfy for the evil there is in one vain thought. You may think it severe, that God should subject His creatures to everlasting sufferings for sin, and never be satisfied with them any more; bit when you have well considered that the Being against whom you sin is the infinitely blessed God, and how God dealt with the angels that fell, you will change your mind.
Oh the depth of the evil of sin! If ever you wish to see how great and horrible an evil sin is, measure it in your thoughts, either by the infinite holiness and excellency of God, who is wronged by it, or by the infinite sufferings of Christ, who died to satisfy for it; and then you will have deeper apprehensions of its enormity.”
