But then, in the next place, this is not a spiritless inefficacious speculation about these things, to know no evil but sin and separation from God, and no blessedness but in the fruition of him; it is not such a knowledge of them as doth not principle motion to pursue after them.  This I grant is part of the image of God, when the Sun of Righteousness, by arising upon the man, hath made day-light in his soul, and by these divine discoveries hath taught him to make the true parallel betwixt things that differ, and to put a just value upon them according to their intrinsic worth.  But this divine illumination doth not consist in a mere notion of such things in the head, nor doth it subsist in enlightening the mind; but in such an impression of God upon the soul, as transforms and changes the heart into his likeness by love.’  Knowledge is but one line, one draught or lineament of the soul’s likeness to him; that alone doth not make up the image, but knowledge rooted in the heart, and engraven on the soul, hining and shewing itself forth in a gospel-adorning conversation, that makes a comely proportion; when the same hand that touched the eye, and turned the man from darkness to light, and gave an heart to know him, that he is the Lord, that doth also circumcise the man’s heart to love the Lord his God, with all his heart, and with all his soul, and with all his mind; and this love manifesting its liveliness, in its constraining power to live to him and for him.  Light without, heat is but wild fire; but light in the mind, begetting heat in the heart, making it burn Godward, Christward, and heavenward; light in the understanding, setting on fire and inflaming the affections, and these shining out in a heavenly conversation, makes up the lively image of God, both in feature and stature, both in proportion and colour.  Faith begins this image, and draws the lineaments; and love bringing forth obedience finishes, and gives it the lively lustre.  The burnings of love in obedience to God is that which illuminates the whole, and makes a man look indeed like him, to whose image he is predestinate to be conform, and then makes him, who is ravished with the charms of that beauty, say, as in a manner overcome thereby, “how fair is thy love, my sister, my spouse?  How much better is thy love than wine, and the smell of thine ointments than all spices?” But consider, that as these beams, which irradiate the soul, are from the Spirit of Christ, so that spiritual heat and warmth come out of the same airth, and proceed from the same author, for our fire burns as he blows, our lamp shines as he snuffs and furnisheth oil.  Men therefore should not indulge themselves in this delusion, to think, that that which will pass for pure religion and undefiled before God, consists either in an outward blameless conversation, or in putting on and wearing an external garb of profession.  No, as the top of it reacheth higher, so the root of it lies deeper; it is rooted in the heart, this
