(2.) There is more close and immediate preparation required, and this I call actual preparation. It is true, indeed, he that is conscientious and careful in the ordinary exercises of religion, hath a great advantage of him that either neglects them or is loose in them, for his heart must needs stand in a nearer disposition to this extraordinary service than the other—as he that is up and hath his clothes on, is more ready to go on his master’s errand than he that is asleep in his bed. Yet, besides this care in our daily walking, there needs some further pains to be taken with his heart to raise it unto such a frame as may comport with this solemn service. The neat housewife, though she endeavours to keep her house clean, yet, against some good time, as they call it, she is more than ordinary curious in washing her rooms, and scouring her vessels, that they might not only be clean but bright; and so should the Christian. Now is the time for thee to scour off the dust thou contractest in thy daily course, and to brighten thy graces unto a further glory that appears in thy everyday walking, to do which will cost pains and require time.
The Christian is like some heavy birds, as the bustard and others, that cannot get upon the wing without a run of a furlong or two; or a great bell that takes some time to the raising of it. Now, meditation is the great instrument thou art to use in this preparatory work. Allow thyself some considerable portion of time, before the day of extraordinary prayer, for thy retirement, wherein thou mayest converse most privately with thy own heart. This cannot be done in a crowd, neither must it be left to the time of engaging in the extraordinary duty. We cannot do both duties together. The husbandman cannot whet his scythe and cut grass at once. Betake thyself therefore to thy closet, and in the first place call thy thoughts off the world, and as much as is possible clear thy soul of all that is foreign to the work thou art about; this is the wiping of the table‑book before we can write anything well on it. Now the more effectually to gather in thy heart to a holy seriousness, and compact thy thoughts together, it were expedient for thee at first to lay before thee the grand importance of the approaching service. Thou art going to stand before the great God, and that very near in an extraordinary duty, wherein thou wilt either sanctify or profane his reverend in a high degree, and accordingly art to expect his love or wrath in some choice blessing or dreadful curse, to be the issue and result of thy undertaking! Gird the loins of thy mind with some such awful apprehensions as these. As natural fear makes the spirits retire from the outward parts of the body to the heart, so this holy fear of miscarrying in so solemn a duty would be a means to call thy thoughts from all exterior carnal objects, and fix them upon the duty in hand; 'In thy fear will I worship,’ Ps. 5:7. Such will the print on the wax be as the sculpture is on the seal. If the fear of God be deeply engraven on thy heart, there is no doubt but it will make a suitable impression on the duty thou performest. Well, now the court is set and silence commanded, a few particulars I shall propound for thy thoughts to go upon in this preparatory work.
