The battle to prevent leprosy was perpetual. The war with sin is the same. And Leviticus is telling us how to win.
Be on guard. Sin crouches at the door waiting to destroy (Genesis 4:7). Sin comes back like a boomerang: when we are tired, bored, and least expecting it. We know its strategies. We know its strength and our weaknesses. Now, we must be on guard against temptation.
Be separate. What is holy has no fellowship* with the unholy and profane (2 Corinthians 6:14). There can be no fellowship between the holy and the unholy – it always dissolves into either a relationship between the unholy and the unholy or breeds discord. Until the leprous are clean, the clean and the unclean cannot have fellowship. The same with sin, two cannot be close until the disease is gone. The same with sin. Instead, we must select companions who spur us onto to love and good works.
*Fellowship does not mean association or even cursory friendship. It means a close, open, and/or deep friendship.
Come with me as we grow in fellowship with each other and our Savior to whom belongs the Amazing Escape from sin and death and the Amazing Journey into glorious life.
