Now, _threshing is useful in loosening the connection between the good corn and the husk_. Of course, if it would slip out easily from its husk, the corn would only need to be shaken. There would be no necessity for a staff or a rod, much less for the feet of horses, or the wheel of a cart to separate it. But there's the rub: our soul not only lieth in the dust, but "cleaveth" to it. There is a fearful intimacy between fallen human nature and the evil which is in the world; and this compact is not soon broken. In our hearts we hate every false way, and yet we sorrowfully confess, "When I would do good, evil is present with me." Sometimes when our spirit cries out most ardently after God, a holy will is present with us, but how to perform that which is good we find not. Flesh and blood have tendencies and weaknesses which, if not sinful in themselves, yet tend in that direction. Appetites need but slight excitement to germinate into lusts. It is not easy for us to forget our own kindred and our father's house even when the king doth most greatly desire our beauty. Our alien nature remembers Egypt and the flesh-pots while yet the manna is in our mouths. We were all born in the house of evil, and some of us were nursed upon the lap of iniquity, so that our first companionships were among the heirs of wrath. That which was bred in the bone is hard to get out of the flesh. Threshing is used to loosen our hold of earthly things and break us away from evil. This needs a divine hand, and nothing but the grace of God can make the threshing effectual. Something is done by threshing when the soul ceases to be bound up with its sin, and sin is no longer pleasurable or satisfactory. Still, as the work of threshing is never done till the corn is separated altogether from the husk, so chastening and discipline have never accomplished their design till God's people give up every form of evil, and abhor all iniquity. When we shake right out of the straw, and have nothing further to do with sin, then the flail will lie quiet. It has taken a good deal of threshing to bring some of us anywhere near that mark, and I am afraid many more heavy blows will be struck before we shall reach the total separation. From a certain sort of sins we are very easily separated by the grace of God early in our spiritual life; but when those are gone, another layer of evils comes into sight, and the work has to be repeated. The complete removal of our connection with sin is a work demanding the divine skill and power of the Holy Ghost, and by him only will it be accomplished. Threshing becomes needful for the sake of our usefulness; for the wheat must come out of the husk to be of service. We can only honor God and bless men by being holy, harmless, undefiled, and separate from sinners. O corn of the Lord's threshing-floor, thou must be beaten and bruised, or perish as a worthless heap! Eminent usefulness usually necessitates eminent affliction.
