"Every branch that beareth fruit, he purgeth it, that it may bring forth more fruit." This purging is another process quite contrary to nature, for the term signifies an inward cleansing. A vine-dresser can prune or trim a branch and thereby practically make it clean outwardly from all unnecessary or harmful sprouts which would hinder it from bearing fruit, but there is no known natural process by which the grafted branch could have its inward conditions changed which would affect its nature. We can see clearly that the entire process of grafting the inferior branch into the good root, and the subsequent purging is wholly contrary to nature, for no man with an object of profit would do any such grafting, neither could anyone reasonably expect the inward conditions of such a graft to become changed. This purging is wrought within for the purpose of an increase of holy fruit. How beautifully it pictures the experience of sanctification, and subsequent work wrought in the soul of the justified fruit-bearing child of God. It is not a pruning of any unholy sprouts, for they are to be wholly kept from sprouting in the process of the life of bearing holy fruit in this justified relation. The branch is now bearing the very fruit of the holy root, but there is something to be done in it that it may bring forth more fruit; it must be purged from its inward depraved dispositions which it possessed from its parent stock--its "old man ... that the body of sin might be destroyed." Before the purging there was much time and energy occupied in keeping its depraved nature from sprouting. The holy nature of the root was indeed being manifested in the production of holy fruit which was a source of satisfaction, but there was that inward consciousness of an unfavorable condition which hindered the root-life from producing in the branch the quantity necessary to the perfect satisfaction of the husbandman, the vine or the branch.
