It is to be remarked, that in proportion as fire approaches its centre, it always approaches rest, although its swiftness increases. It is the same with the soul: as soon as sin ceases to hold it back, it seeks indefatigably to find God; and if it were not for sin, nothing could impede its course, which would be so speedy, that it would soon attain its end. But it is also true that, in proportion as it approaches God, its speed is augmented, and at the same time becomes more peaceful; for the rest, or rather the peace, since it is not at rest, but is pursuing a peaceful course, increases so that its peace redoubles its speed, and its speed increases its peace. The hindrances, then, arise from sins and imperfections, which arrest for a time the course of the soul, more or less, according to the magnitude of the fault. Then the soul is conscious of its activity, as though when fire was going on towards its centre, it encountered obstacles, such as pieces of wood or straw: it would resume its former activity in order to consume these obstacles or barriers, and the greater the obstacle the more its activity would increase. If it were a piece of wood, a longer and stronger activity would be needed to consume it; but if it were only a straw, it would be burned up in a moment, and would but very slightly impede its course. You will notice that the obstacles which the fire would encounter would only impart to it a fresh stimulus to surmount all which prevented its union with its centre; again, it is to be remarked, that the more obstacles the fire might encounter, and the more considerable they might be, the more they would retard its course; and if it were continually meeting with fresh ones, it would be kept back, and prevented from returning whence it came. We know by experience, that if we continually add fuel to fire, we shall keep it down, and prevent its rising. It is the same with the souls of men. Their instincts and natural propensities lead them towards God. They would advance incessantly, were it not for the hindrances they meet. These hindrances are sins and imperfections, which prove the greater obstacles in the way of their return to God, according as they are serious and lasting; so that if they continue in sin, they will never reach their end. Those, therefore, who have not sinned so grossly as others, should advance much more rapidly. This usually is the case, and yet it seems as though God took pleasure in making "grace abound where sin has most abounded" (Rom. v. 20). I believe that one of the reasons of this, to be found in those who have not grossly sinned, is their estimation of their own righteousness, and this is an obstacle more difficult to surmount then even the grossest sins, because we cannot have so great an attachment to sins which are so hideous in themselves, as we have to our own righteousness; and God, who will not do violence to liberty, leaves such hearts to enjoy their holiness at
