Charles H. Spurgeon on Psalms 119:32

Enlarge my heart. It is said of Solomon, that he had "a large heart, (the same word that is used here,)as the sand of the sea shore:" that is a vast, comprehensive spirit, that could fathom much of nature, both its greater and lesser things. Thus, I conceive, the enlargement of the heart comprises the enlightening of the understanding. There arises a clearer light there to discern spiritual things in a more spiritual manner; to see the vast difference betwixt the vain things the world goes after, and the true solid delight that is in the way of God's commandments; to know the false blush of the pleasures of sin, and what deformity is under that painted mask, and not be allured by it; to have enlarged apprehensions of God, his excellency, and greatness and goodness; how worthy he is to be obeyed and served; this is the great dignity and happiness of the soul; all other pretensions are low and poor in respect of this. Here then is enlargement to see the purity and beauty of his law, how just and reasonable, yea, how pleasant and amiable it is; that his commandments are not grievous, that they are beds of spices; the more we walk in them, still the more of their fragrant smell and sweetness we find.
