Constitution-Sins
They that name the name of Christ, let them depart from their constitution-sin, or if you will, the sin that their temper most inclines them to. Every man is not alike inclined to the same sin, but some to one, and some to another. Now, let the man that professes the name of Christ religiously consider with himself, “Unto what sin or vanity am I most inclined? is it pride? is it covetousness? is it fleshly lust?” and let him labor by all means to leave off and depart from that. This is that which David called his own iniquity, and saith, “I was also upright before him, and I kept myself from mine iniquity.” Psa. 18:23. Rightly are these two put together, for it is not possible that he should be an upright man that indulgeth or countenanceth his constitution-sin; but on the contrary, he that keeps himself from that will be upright as to all the rest; and the reason is, because if a man has grace to trample upon and mortify his darling, his bosom, his only sin, he will more easily and more heartily abhor and fly the rest.
And indeed, if a man will depart from iniquity, he must depart from his darling sin first; for as long as that is entertained, the other, at least those that are most suiting to that darling, will always be haunting of him. There is a man that has such and such haunt his house and spend his substance, and would be rid of them, but cannot; but now, let him rid himself of that for the sake of which they haunt his house, and then he shall with ease be rid of them. Thus it is with sin. There is a man that is plagued with many sins, perhaps because he embraceth one; well, let him turn that one out of doors, and that is the way to be rid of the rest. Keep thee from thy darling, thy bosom, thy constitution-sin.
Among the motives to prevail with thee to fall in with this exhortation, are,
1. There can no great change appear in thee, make what profession of Christ thou wilt, unless thou cast away thy bosom sin. A man’s constitution-sin is, as I may call it, his visible sin; it is that by which his neighbors know him and describe him, whether it be pride, covetousness, lightness, or the like. Now, if these abide with thee, though thou shouldst be much reformed in thy notions and in other parts of thy life, yet say thy neighbors, “He is the same man still: his faith has not saved him from his darling. He was proud before, and is proud still; was covetous before, and is covetous still; was light and wanton before, and is so still; he is the same man, though he has got a new mouth.” But now, if thy constitution-sin be parted with, if thy darling be cast way, thy conversion is apparent; it is seen of all; for the casting away of that is death to the rest, and ordinarily makes a change throughout.
2. So long as thy constitution-sin remains, as winked at by thee, so long thou art a hypocrite before God, let thy profession be what it will; also, when conscience shall awake and be commanded to speak to thee plainly what thou art, it will tell thee so, to thy no little vexation and perplexity.
