The same sacrifices which atoned for sin and guilt were applied to cleansing of skin diseases. The same Christ whose death on the cross saved you from hell can also clean up your life on earth today.
The LORD calls us to cleansing:
“Come now, let us reason together, says the LORD: though your sins are like scarlet, they shall be as white as snow; though they are red like crimson, they shall become like wool.” (Isaiah 1:18).
LORD, we surrender to you our today, as well as our eternal tomorrow.
