Others, who will allow that sin is of a far larger extent, and includes in it that which prevails in the heart, as well as renders itself visible in the life, or contains in it the omission of duties, as well as the actual commission of known sins; these often take a preposterous method to mortify it: if they are sensible of the guilt that is contracted hereby, they use no other method to be discharged from it, but by pretending to make atonement, either by confessing their sins, using endeavours to abstain from them, or by the performance of some duties of religion, by which they think to make God amends for the injuries they have offered to him thereby: but this is so far from mortifying sin, that it increases the guilt thereof, and causes it to take deeper root, and afterwards to break forth in a greater degree; or else tends to stupify the conscience, after which they go on in a way of sin, with carnal security, and without remorse.
Others think, that to mortify sin, is nothing else but to subdue and keep under their passions, at least, to such a degree that they may not, through the irregularity and impetuous violence thereof, commit those sins which they cannot but reflect upon with shame, when brought into a more calm and considerate temper of mind; and, in order thereunto, they subject themselves to certain rules, which the light of nature will suggest, and the wiser Heathen have laid down to induce persons to lead a virtuous life; and they argue thus with themselves, that it is below the dignity of the human nature, for men to suffer their passions to lead their reason captive, or to do that which betrays a want of wisdom as well as temper; and if by this means the exorbitancy of their passions is abated, and many sins, which are occasioned thereby, prevented, they conclude their lives to be unblemished, and sin subdued; whereas this is nothing else but restraining the fury of their temper, or giving a check to some sins, while sin in general remains unmortified.
As to the methods prescribed by some Popish casuists, of emaciating, or keeping under the body by physic, or a sparing diet, and submitting to hard penances, not only to atone for past sins, but prevent them for the future, these have not a tendency to strike at the root of sin, and therefore are unjustly called a mortifying of it. For though an abstemious regular way of living be conducive to answer some valuable ends, and without it men are led to the commission of many sins; yet this is no expedient to take away the guilt thereof; neither is the enslaving, captivating, and prevailing power of indwelling sin, that discovers itself in various shapes, and attends every condition and circumstance of life, sufficiently subdued hereby.
And those common methods that many others take, which are of a different nature, namely, when they resolve, though in their own strength, to break off their sins by repentance; or, if their resolutions to lead a virtuous life are weak, and not much regarded by them, endeavour to strengthen them, this will not answer their end, sin will be too strong for all their resolutions, and the engagements with which they bind themselves, will be like the cords with which Sampson was bound, which were broken by him like threads. If we rely on our own strength, how much soever we may be resolved to abstain from sin at present, God will make us sensible of our weakness, by leaving us to ourselves; and then, how much soever we resolve to abstain from sin, it will appear that it is far from being mortified, or subdued by us. Therefore we conclude, that this cannot be performed, but by going forth in the name and strength of Christ, who is able to keep us from falling; or, when fallen, to recover us; and this will be found, in the end, to be the best expedient for the promoting this branch of our sanctification; which leads us to consider,
III. That, in the farther carrying on of this work of sanctification, we are enabled to walk with God, or before him, in holiness and righteousness. We are first made alive in regeneration, and then put forth living actions, which some call vivification, as distinguished from that part of sanctification, which has been already considered, namely, mortification of sin.
This is what we may call leading an holy life, whereby we are to understand much more than many do, who suppose, that it consists only in the performance of some moral duties, that contain the external part of religion, without which there would not be the least shadow of holiness; and in performing those duties which we owe to men in the various relations which we stand in to them; or, at least, in keeping ourselves clear from those pollutions which are in the world through lust, 2 Pet. i. 4. The Pharisee, in the gospel, thought himself an extraordinary holy person, because he was no extortioner, nor unjust, nor adulterer; but fasted, paid tithes, and performed several works of charity; and many are great pretenders to it, who have no other than a form of godliness, without the power of it, or who are more than ordinarily diligent in their attendance on the ordinances of God’s appointment; though they are far from doing this in a right way, like those whom the prophet speaks of, who are said to seek God daily, and to delight to know his ways, as a nation that did righteousness, and forsook not the ordinance of their God; though at the same time, they are said to fast for strife and debate, and to smite with the fist of wickedness, Isa. lviii. 2. But, that we may consider several other things, which are contained in a person’s leading an holy life, let it be observed,
1. That our natures must be changed, and therefore sanctification always supposes and flows from regeneration: there must be grace in the heart, or else it can never discover itself in the life; the root must be good, or else the tree cannot bring forth good fruit; the spring of action must be cleansed, otherwise the actions themselves will be impure. Some persons, who are generally strangers to the internal work of grace, are very apt to insist much on the goodness of their hearts, and this is sometimes pleaded in excuse for the badness of their lives; whereas they never had a due sense of the plague and perverseness of their own hearts. Good actions must proceed from a good principle, otherwise persons are in an unsanctified state; and, as they must be conformable to the rule laid down in the word of God, and performed in a right manner, and to the glory of God as to the end designed thereby; so they must be performed by faith, whereby we depend on Christ for assistance and acceptance, as being sensible of our constant work and business, whereby we are said to walk with God, as well as live to him.
2. In order to our leading an holy life, we must make use of those motives and inducements thereunto, that are contained in the gospel; and to encourage us herein,
(1.) We are to have in our view that perfect pattern of holiness which Christ has given us; he has left us an example that we should follow his steps, 1 Pet. ii. 21. Whatever we find in the life of Christ, prescribed for our imitation, should be improved to promote the work of sanctification; his humility, meekness, patience, submission to the divine will, his zeal for the glory of God, and the good of mankind, and his unfainting perseverance in pursuing the end for which he came into the world, are all mentioned, in scripture, not barely that we should yield an assent to the account we have thereof in the gospel history; but that the same mind should be in us, which was also in him, Phil. ii. 5. or, as the apostle says, He that saith he abideth in him, ought himself also to walk even as he walked, 1 John ii. 6. And to this we may add, that we ought to set before us the example of others, and be followers of them, so far as they followed him: their example, indeed, is as much inferior to Christ’s as imperfect holiness is to that which is perfect; but yet it is an encouragement to us, that in following the footsteps of the flock, we have many bright examples of those, who through faith and patience, inherit the promises.
(2.) Another motive to holiness is the love of Christ, expressed in the great work of our redemption, and in that care and compassion which he has extended towards us in the application thereof, in all the methods he has used in the beginning and carrying on the work of grace, in which we may say, hitherto he hath helped us: this ought to be improved so as to constrain us, 2 Cor. v. 14. as he has hereby laid us under the highest obligation to live to him. And as love to Christ is the main ingredient in sanctification; so when by faith we behold him as the most engaging and desirable object, this will afford a constant inducement to holiness.
