From J. L. Dagg’s Manual of Theology, pg 49:
Love to God implies cordial approbation of his moral character. His natural attributes, eternity, immensity, omnipotence, etc., may fill us with admiration; but these are not the proper objects of love. If we worship him in the beauty of holiness, the beauty of his holiness must excite the love of our hearts. As our knowledge of these moral perfections increases, our delight in them must increase; and this delight will stimulate to further study of them; and to a more diligent observation of the various methods in which they are manifested. The display of them, even in the most terrible exhibitions of his justice, will be contemplated with reverent, but approving awe; and their united glory, as seen in the great scheme of redemption by Christ, will be viewed with unmixed and never-ceasing delight.
