3. The essential necessary truths of your religion, must imprint the image of God upon your hearts, and must dwell there continually, and you must live upon them as your bread, and drink, and daily necessary food: all other points must be studied in subserviency to those: all lesser duties must be used as the exercise of the love of God or man, and of a humble heavenly mind. The articles of your creed, and points of catechism, are fountains ever running, affording you matter for the continual exercise of grace: it is both plentiful and solid nourishment of the soul, which these great substantial points afford. To know God the Creator, Redeemer, and Sanctifier, the laws and covenant of God, and his judgment, and rewards and punishments, with the parts and method of the Lord's prayer, which must be the daily exercise of our desires, and love, this is the wisdom of a christian; and in these must he be continually exercised. You will say perhaps that the apostle saith, Heb. vi. 1, "Leaving the principles of the doctrine of Christ, let us go on to perfection, not laying again the foundation of repentance from dead works," &c. _Answer_ 1. By "leaving" he meaneth not passing over the practice of them as men that have done with them, and are past them; but his leaving at that time to discourse of them, or his supposing them taught already: though he lay not the foundation again, yet he doth not pluck it up. 2. By "principles" he meaneth the first points to be taught, and learnt, and practised: and indeed regeneration and baptism is not to be done again: but the essentials of religion which I am speaking of, contain much more: especially to "live in the love of God, which Paul calls the more excellent way," 1 Cor. xii. and xiii. 3. Going on to perfection, is not by ceasing to believe and love God, but by a more distinct knowledge of the mysteries of salvation, to perfect our faith, and love, and obedience. The points that opinionists call higher, and think to be the principal matter of their growth, and advancement in understanding, are usually but some smaller, less necessary truths, if not some uncertain, doubtful questions. Mark well 1 Tim. i. 4; vi. 4; 2 Tim. ii. 23; Tit. iii. 9, compared with John xvii. 3; Rom. xiii. 8-10; 1 Cor. xiii.; 1 John iii.; 1 Cor. i. 23; xv. 1-3; ii. 2; Gal. vi. 14; James ii.; iii. 1. _Direct._ V. Be very thankful for the great mercy of your conversion: but yet overvalue not your first degrees of knowledge or holiness, but remember that you are yet but in your infancy, and must expect your growth and ripeness as the consequent of time and diligence.
