incense_, when they saw _the leprosy_ upon him; so do thou thrust those thoughts from the temple of thy heart, which have the badge of God's prohibition upon them. § 21. (2.) Be sure to set upon this work with the greatest solemnity of heart and mind. There is no trifling in holy things. _God will be sanctified in them that come nigh him._[362] These spiritual, excellent, soul-raising duties, are if well used, most profitable; but when used unfaithfully, most dangerous. Labor therefore to have the deepest apprehensions of the presence of God, and his incomprehensible greatness. If queen Esther must not draw near, till _the king hold out the sceptre_; think, then, with what reverence thou shouldst approach Him, who made the worlds with the word of his mouth, who upholds the earth as in the palm of his hand, who keeps the sun, moon, and stars in their courses, and who sets bounds to the raging sea. Thou art going to converse with Him, before whom the earth will quake, and Devils do tremble, and at whose bar thou and all the world must shortly stand, and be finally judged. O think! "I shall then have lively apprehensions of His Majesty. My drowsy spirits will then be awakened, and my irreverence be laid aside; and why should I not now be roused with the sense of his greatness, and the dread of his name possess my soul?" Labor also to apprehend the greatness of the work which thou attemptest, and to be deeply sensible both of its importance and excellency. If thou wast pleading for thy life at the bar of an earthly judge, thou wouldst be serious; and yet that would be a trifle to this. If thou wast engaged in such a work as David against Goliath, on which the welfare of a kingdom depended; in itself considered, it were nothing to this. Suppose thou wast going to such a _wrestling_ as Jacob's, or to see the sight which the _three disciples saw in the mount_; how seriously, how reverently, wouldst thou both approach and behold! If but an angel from heaven should appoint to meet thee, at the same time and place of thy contemplations; with what dread wouldst thou be filled? Consider then, with what a spirit thou shouldst meet the Lord, and with what seriousness and awe thou shouldst daily converse with him. Consider also the blessed issue of the work, if it succeed: it will be thy admission into the presence of God, and the beginning of thy eternal glory on earth; a means to make thee live above the rate of other men, and fix thee in the next room to the angels themselves, that thou mayest both live and die joyfully. The prize being so great, thy preparations should be answerable. There is none on earth live such a life of joy and blessedness, as those that are acquainted with this heavenly conversation. The joys of all other men are but like a child's play, a fool's laughter, or a sick man's dream of health. He that trades for heaven is the only gainer, and he that neglects it is the only loser. How seriously, therefore, should this work be done?
