_Direct._ II. To this end you must know in their several degrees, what subjects are in themselves most excellent to be meditated on. As the first and highest is the most blessed God himself, and the glorious person of our Redeemer, and the New Jerusalem or heaven of glory, where he is revealed to his saints. And then, the blessed society which there enjoyeth him, and the holy vision, love, and joy, by which he is enjoyed. And next is the wonderful work of man's redemption, and the covenant of grace, and the sanctifying operations of the Holy Ghost, and all the graces that make up God's image on the soul. And then is the state and privileges of the church, which is the body of Christ, for whom all this is done and prepared. And next is the work of the gospel, by which this church is gathered, edified, and saved. And then, the matter of our own salvation, and our state of grace, and way to life. And then, the salvation of others. And then, the common, public good, in temporal respects. And then, our personal, bodily welfare. And next, the bodily welfare of our neighbours. And lastly, those things that do but remotely tend to these. This is the order of desirableness and worth, which will tell you what should have estimative precedency in your thoughts and prayers.
_Direct._ III. You must also know what subject is then most seasonable for your thoughts, and refuse even an unseasonable good. For good may be used by unseasonableness to do hurt. It may be thrust in by the tempter, on purpose to divert you from some greater good, or to mar some other duty in hand; so he will oft put in some good meditation to turn you from a better, or in the midst of sermon or prayer: or if he see you out of temper to perform a duty of meditation, or that you have no leisure, without neglecting your more proper work, he will then drive you on, that by the issue he may discourage and hurt you, and make the duty unprofitable and grievous to you, and make you more averse to it afterwards. Untimely duty may be no duty, but a sin, which is covered with the material good. As the Pharisees' sabbath-rest was, when mercy called them to violate it.
_Direct._ IV. Examine well, and determine of the end and use of your meditations, before you set upon them, and then labour to fit them to that special end. The end is first in the intention, and from the love of it the means are chosen and used. If it be knowledge that you are to increase, it is evidence of truth, with the matter to be known, in a convincing, scientifical way, that you must meditate on. If it be divine belief that is to be increased or exercised, it is divine revelations, both matter, and evidence of credibility, which you have to meditate on. If you would excite the fear of God, you have his greatness, and terribleness, his justice, and threatenings to meditate on. If you would excite the love of God, you have his goodness, mercy, Christ, and promises to meditate on. If you would prepare for death and judgment, you have your hearts to try, your lives to repent of, your graces to discover, and revive, and exercise, and your soul's diseases to feel, and the remedies to apply: so whenever you mean to make any thing of a set meditation, determine first of the end, and by it of the means.
_Direct._ V. Clear up the truth of things to your minds as you can, before you take much pains to work them on your affections, lest you find after that you did but misinform yourselves, and bestow all your labour in vain, to make deluding images on your minds, and bring your affections to bow before them. As many have done by espousing errors, who have laid out their zeal upon them many years together, and made them the reason of hatred, and contention, and bitter censurings of opposing brethren; and have made parties, and divisions, and disturbances in the church for them, and after so many years' zealous sinning, have found them to be but like Michal's image, a man of straw instead of David; and that they made all this filthy pudder but in a dream.
