“And there came a leper to Him, beseeching Him, and kneeling down to Him, and saying unto Him, ‘If Thou wilt, Thou canst make me clean’. And Jesus, moved with compassion, put forth His hand, and touched him, and saith unto him, ‘I will; be thou clean.’ And as soon as He had spoken, immediately the leprosy departed from him, and he was cleansed.” Mark 1:40-42 (KJB)
In the Old Testament Law people were forbidden to touch the leprous individual. Families were separated because of this dreadful skin, and joint plague. They were required to in the presence of others call out “Unclean, unclean” as they approached a group of people or a single individual. To touch a leper made you unclean, and could not enter the house of God until you were declared clean.
In the above verse Jesus, in the early part of His ministry, touched the unclean leper. Jesus the clean, the holy, the righteous Son of God touched the unclean, the unholy, the unrighteous. O how He was ridiculed, mocked, and later died for such a seeming betrayal of the law.
What He did for this leper is what He did for the world when He was nailed to the cross. He took on Himself the infirmities of us all. He was stricken by His Father because He became what His Father, and He Himself hated. He became our sin (2 Corinthians 5:21); and the wrath of Almighty God was poured out upon Him.
We are or were as unclean as that leper before Holy God. We cannot approach God. We cannot know God in that unclean condition. God made a way through the death, burial, and resurrection of Jesus Christ.
Confess you are unclean, that you are a sinner; repent of your sins, and call on the name of Jesus. He will hear you, and deliver you from your sin and uncleanness; and you will have eternal life in His presence forever.
