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.
