§ 19. (IV.) I am next to advise thee concerning the preparations of thy heart for this heavenly contemplation. The success of the work much depends on the frame of thy heart. When man's heart had nothing in it to grieve the Spirit, it was then the delightful habitation of his Maker. God did not quit his residence there, till man expelled him by unworthy provocations. There was no shyness or reserve, till the heart grew sinful, and too loathsome a dungeon for God to delight in. And was this soul reduced to its former innocency, God would quickly return to his former habitation; yea, so far as it is renewed and repaired by the Spirit, and purged from its lusts, and beautified with his image, the Lord will yet acknowledge it as his own; Christ will manifest himself unto it, and the Spirit will take it for his temple and residence. So far as the heart is qualified for conversing with God, so far it usually enjoys him. Therefore, _with all diligence keep thy heart, for out of it are the issues of life_.[361] More particularly, [Footnote 361] Proverbs iv, 23. § 20. (1.) Get thy heart as clear from the world as thou canst. Wholly lay by the thoughts of thy business, troubles, enjoyments, and every thing that may take up any room in thy soul. Get it as empty as thou possibly canst, that it may be the more capable of being filled with God. If thou couldst perform some outward duty with a piece of thy heart, while the other is absent, yet this duty above all I am sure thou canst not. When thou shalt go into the mount of contemplation, thou wilt be like the covetous man at the heap of gold, who, when he might take as much as he could, lamented that he was able to carry no more; so thou wilt find as much of God and glory as thy narrow heart is able to contain, and almost nothing to hinder thy full possession, but the incapacity of thy own spirit. Then thou wilt think, "O that this understanding, and these affections, could contain more! It is more my unfitness than any thing else, that even this place is not my heaven. _God is in this place and I know it not._ This _mount is full of chariots of fire_, but mine eyes are shut, and I cannot see them, O the words of love Christ hath to speak, and wonders of love he hath to shew, but I cannot bear them yet! Heaven is ready for me, but my heart is unready for heaven." Therefore, reader, seeing thy enjoyment of God in this contemplation much depends on the capacity and disposition of thy heart, seek him here, if ever, with all thy soul. Thrust not Christ into _the stable, and the manger_, as if thou hadst better guests for the chief rooms. Say to all thy worldly business and thoughts, as Christ to his disciples, _Sit ye here, while I go and pray yonder_. Or as Abraham to his servants, when he went to offer Isaac, _Abide ye here, and I will go yonder and worship, and come again to you_. Even as _the priests thrust king Uzziah out of the temple_, where he presumed _to burn
