When we think of the term "unclean" in Scripture, we usually associate it with matters of the soul. Unclean spirits attack and torment. Sin pollutes us. The sins perpetrated on us leave us feeling contaminated.
And in response Jesus says, "I am willing; be cleansed." (8:3) What marvelous words those are! Here the Lord’s heart is opened to us and we see His great desire to make us clean in both soul and body. This is the very purpose for which the Son of God was made man, to purify you from all that ails your flesh and spirit. Later in this chapter, it is written, "He Himself took our sicknesses and bore our infirmities." (8:17) This is your Savior, the One who took into His own flesh all that attacks your flesh. He knows, He has felt your sickness in the deepest way possible. In His scourging and on the cross, His body was opened up and laid bare to every pathogen that threatens your life. He died a bloody, infected, unclean mess. But by that very death, He conquered all your sickness and your disease and the grave itself. For in the body of God made flesh, all corruptions of the flesh met their match and their end. Jesus’ body did not see decay or corruption in the grave (Ps. 16:10). By the wounds of Christ you are healed and cleansed. The One crucified and now risen in the flesh is your cure.
"I am willing; be cleansed." This our Lord spoke to you in your baptism, washing you, giving you the sure hope that your lowly body will be transformed to be like His glorious body (Philippians 3:21). Every divine service you hear those words. For in the absolution God speaks words that are life to you and health to all your flesh (Proverbs 4:22). And the blood of Jesus, God’s Son, which you receive at His table, cleanses you from all sin (1 John 1:7). It is surely the medicine of immortality and the guarantee of health and marvelous wholeness that will be yours in the resurrection of the body and the life of the world to come.
Jesus can make you clean. He is willing. Be cleansed.
