The symptoms described in the Torah that might potentially be diagnosed as biblical leprosy involve decomposition, decay, and putrefaction—corruption of the flesh. The laws of the sacrifices teach that God’s Sanctuary shuns death, corruption, and decay.
God’s Sanctuary represents immortality and incorruptibility. In His presence, there is no death, no decay, and no decomposition. Therefore, He bans from His Sanctuary the disease that represents a living decomposition. Leprosy involves an ongoing, visible progression toward physical corruption. It is the antithesis of the immortal and incorruptible world represented in God’s Sanctuary.
Leprosy also acts as an archetype for all human sickness. Sickness results from the breakdown of the flesh. Death follows. Leprosy graphically represents that progression.
Sickness, death, and decay have no place in God’s presence. His Sanctuary on earth reflects that heavenly Sanctuary.
Yeshua provides the solution to the leprosy problem. Spiritually, He did not suffer the leprosy-like infection of sin. Physically, His flesh did not suffer corruption: “For You will not abandon my soul to Sheol; nor will You allow Your Holy One to undergo decay.” Through His resurrection from the dead, His flesh passed from the mortal to the immortal and from the corruptible to the incorruptible. His resurrected body remains real human flesh, regenerated into an imperishable spiritual body. Therefore, He is the perfect, eternal priest, able to serve forever in the incorruptible Sanctuary.
Perhaps this helps explain why the healing of lepers occupied such a central concern in the ministry of the Master. Not only did He heal many lepers Himself, but He gave His twelve disciples authority to heal leprosy as evidence of the kingdom of heaven. Leprosy symbolizes the sin-laden human condition, destined for death and decay. Each time the Master healed a leper, it betokened a reversal of that corrupted, mortal state. Every leper healed of his affliction was a testimony that the kingdom of heaven was at hand.
Who will set me free from the body of this death? Thanks be to God through Yeshua the Messiah our Master! (Romans 7:24-25)
