15. When we defile ourselves with new transgressions and failings, he hath provided a fountain for us to wash in; "a fountain opened to the house of David, and to the inhabitants of Jerusalem, for sin and for uncleanness," Zech. xiii. 1; and this fountain is his blood, which cleanseth from all sin, Heb. ix. 14. 1 John i. 7. Rev. i. 5. 16. He is set before us as a copy and pattern, that we "should walk even as he walked," 1 John ii. 6. "He left us an example that we should follow his steps," 1 Pet. ii. 21. But we should beware to separate this consideration from the preceding, as antichristian Socinians do, who will have Christ only to be a copy. 17. He hath overcome Satan, our arch enemy, and hath destroyed his works, 1 John iii. 8. He came to destroy the works of the devil; and in particular, his works of wickedness in the soul. Thus he is a conqueror and the captain of our salvation. 18. As he hath purchased, so hath he appointed ordinances, for the laying of the foundation, and carrying on this work of sanctification; both word and sacraments are appointed for that; the word to convert and to confirm, John xvii. 17. "Sanctify them through thy truth, thy word is truth," said Christ. The word is given as the rule; and also through the means thereof is life and strength conveyed to the soul, "to perfect holiness in the fear of God," 1 Pet. ii. 2. And the sacraments are given to strengthen and confirm the soul in the ways of God. 19. As he hath laid down strong encouragements to his followers, to hold on in the way of holiness, many great and precious promises, by which they may be made partakers of the divine nature, 2 Pet. i. 4; and by which they are encouraged to cleanse themselves from all filthiness of the flesh and spirit, 2 Cor. vii. 1; and many motives to hold on and continue; so hath he rolled difficulties out of the way, whether they be within us, or without us, and thereby made the way easy and pleasant to such as walk in it; so as they may now run the way of his commandments, and walk and not weary, and run and not be faint. Nay, 20. We would remember for our encouragement and confidence, that in carrying on of this work lieth the satisfaction of the soul, and the pleasure of the Lord that must prosper in his hand, and thus he seeth his seed, and hath of the travail of his soul, and is satisfied. These particulars, rightly considered, will discover unto us, what a noble ground for sanctification is in Christ laid down for believers, which they may, and must by faith grip to, that they may grow in grace, and grow up in Christ, and perfect holiness; and what a wonderful contrivance of grace this is, wherein all things are made so sure for believers, Christ becoming all things to them, and paving a royal and sure way for them; sure for them, and glorious to himself!
