Purge me with hyssop, and I shall be clean;

   wash me, and I shall be whiter than snow.

Psalm 51: 7

David knew something about sin, and he was acutely aware of the harm that his wandering heart caused to his relationship with God and to his ability to remain close to people, too. So, I think that these words are both a lament and a strong request. David is sorrowful for the sin in his life, and he desires to have the Lord perform His cleansing work upon his body and in his heart. The rough surfaced leaves of the hyssop plant were used to ceremonially cleanse people who had become defiled by dead bodies and by contact with lepers. A bird was sacrificed and the hyssop branch was dipped in its blood so that the blood could be sprinkled on the person who was unclean but repentant for the totality of his sin. The priest would then pronounce the penitent clean, and thus, it was acceptable for him to participate in temple worship or in other forms of sacred rights and ritual. In other words, the person who had repented of his sin and undergone the cleansing ritual was then acceptable to be in the presence of God.

All people are born into a similar condition and many of us find ourselves in a like place in life as did David. We are sinners from birth. We do not get to choose whether we will be perfectly obedient to God or whether we will rebel against His love, righteousness, and call to holiness. People follow the path of our parents just as they adhered to the one that had been established by the many generations that came before them. When the Apostle Paul declared that, “All have sinned and fall short of the glory of God…” he truly meant to be all-inclusive. None of us get to escape this reality, and no one has an answer to our separation from God other than God’s own answer, which is found in Jesus Christ alone and that is made available to all of us by and through Christ’s sacrifice on the cross and God’s resurrection of Him from among the dead. That is it! There is nothing else and no other way to be made righteous and holy in God’s eyes. So, there is no alternative to Jesus if we wish to dwell in the presence of God.

Jesus, through His cross, has eliminated the need for dead birds and rough branches. He has also taken over the position and the authority that had previously been granted to human priests, for Christ alone has God’s endorsement to pronounce people cleansed of sin and so, rightly fit to be in God’s perfect and holy presence. The work that those priests did was temporary at best, but the work that Christ does lasts for all of eternity. The blood that was shed in sacrifice upon Christ’s cross penetrates much deeper than the surface so that the soul of anyone who turns to Christ is not just touched by a few of its purifying drops but it is washed clean and made pure and acceptable to a Holy God. The bright snow of a winter’s day covers over and obscures the dirt and the decay that is a part of life in our world. So too does Christ cover our brokenness and sin with His cleansing blood; however, the snow melts and its effect dissipates with time, but Christ’s pure whiteness lasts for all of eternity.
