Now, to preserve thy affections in prayer warm and lively, let it be thy care to chase and stir up the natural heat that is undoubtedly in thee, if a Christian, by the serious consideration of thy sins, wants, and mercies. While thou art pondering on these, thine eye will affect thine heart. They will, as Abishag did to David, by laying them in thy bosom, bring thy soul to a kindly heat in those affections which thou art to act in the several parts of prayer. Thy sins reviewed, and heightened with their aggravations, will make the springs of godly sorrow to rise in thy heart. Canst thou choose but mourn when thou shalt read thy several indictments to thy guilty soul, now called to hold up its hand at the bar of thy conscience? Canst thou hear how the holy law of God hath been violated, his Spirit grieved, and his Son murdered by thy bloody hands, and this when he hath been treating thee mercifully, and not mourn? Surely, should a man walk over a field after a bloody battle hath been fought, and there see the bodies, though of his enemies, lying weltering in their blood, his heart could not but then relent, though in the heat of battle his fury shut out all thoughts of pity. But what if he should spy a father or a dear friend dead upon the place, of the wounds which his unnatural hand had given, would not his bowels turn? Yes, surely, if he carried the heart of a man in his bosom. Thou mayest guess, Christian, by this, what help such a mediation would afford toward the breaking of thy heart for thy sins. Certainly it would make thee throw away that unhappy dagger which was the instrument to give those deep stabs to the heart of Christ—and this is the best mourning of all. Again, thy wants well weighed would give wings to thy desires. If once thou wert possessed with the true state of thy affairs—how necessary it is for thee to have supplies from heaven, or to starve and die. And so in the rest, &c.
Third Cause. A third cause of roving thoughts, is encumbrance of worldly cares. It is no wonder that man can enjoy no privacy with God in a duty, who hath so many from the world rapping at his door to speak with him when he is speaking with God. Periclitatur pietas in negotiis—religion never goes in more danger than when in a crowd of worldly business. If such a one prays, it is not long before something comes in his head to take him off. ‘Isaac went out to meditate,...and behold the camels.’ The world is soon in such a one's sight. He puts forth one hand to heaven in a spiritual thought, but soon pulls it back, and a worldly one steps before it, and so makes a breach upon his duty. ‘A dream,’ Solomon tells us, ‘cometh through a multitude of business.’ And so do dreaming prayers. They are made up of heterogeneous independent thoughts. The shop, barn, warehouse are unfit places for prayer—I mean the shop in the heart, and the barn in the heart. I have read of one who was said to be a walking library, because he left not his learning with his books in his study, but carried it about with him wherever he went, in his memory and judgment, that had digested all he read, and so made it his own. And have we not too many walking shops and barns, who carry them to bed and board, church and closet? And how can such pray with a united heart, who have so many sharers in their thoughts? O anima sancta sola esto, anne nescis verecundum habes Sponsum!—O, holy soul, get thee alone, if thou wouldst have Christ give thee his loves. Knowest thou not thou hast a modest husband? Indeed he gives the soul not his embraces in a crowd, nor the kisses of his lips in the market. Jacob sends away his company to the other side of the river, and then God gave him one of the sweetest meetings he had in all his life. Let him now pray even a whole night if he will, and welcome. Now, Christian, for thy help against these—
