Myrrh may well be chosen to typify Jesus because of its preciousness, its perfume, its pleasantness, its healing, preserving, disinfecting qualities, and its connection with sacrifice. But why is He compared to "a sachet of myrrh"?
First, because it speaks of plenty. He is not a drop of it—He is a basketful. He is not a sprig or flower of it, but a whole bundle. There is enough in Christ for all my needs; do not let me be slow to avail myself of Him.
Our well-beloved is compared to a "sachet," again, for variety, for there is in Christ not only the one thing needful, but "in him the whole fullness of deity dwells bodily";1 everything needful is in Him. Consider the numerous aspects of Christ, and you will see a marvelous variety—Prophet, Priest, King, Husband, Friend, Shepherd. Consider Him in His life, death, resurrection, ascension, second coming; view Him in His virtue, gentleness, courage, self-denial, love, faithfulness, truth, righteousness—everywhere He is a sachet of preciousness.
He is a "sachet of myrrh" for preservation—not loose myrrh tied up, but myrrh to be stored in a container. We must value Him as our best treasure; we must prize His words and His ordinances; and we must keep our thoughts of Him and our knowledge of Him as under lock and key, in case the devil should steal anything from us.
Furthermore, Jesus is a "sachet of myrrh" for specialty. The emblem suggests the idea of distinguishing, discriminating grace. From before the foundation of the world, He was set apart for His people; and He gives His perfume only to those who understand how to enter into communion with Him, to have close dealings with Him—blessed people whom the Lord has admitted into His secrets, and for whom He sets Himself apart.
Choice and happy are those who can say, "My beloved is to me a sachet of myrrh."
