How does the story of Moses' hand turning leprous illustrate sin?

In God's demonstration to Moses, the leprous hand represents the destructive and all-pervasive nature of sin in humanity. When Moses placed his hand in his bosom and drew it out leprous, it illustrated how sin corrupts and ultimately leads to death. However, God's command to put the hand back and have it restored signifies the cleansing and renewing power found in Him. Just as leprosy symbolizes our sinful condition, the healing of Moses’ hand points to the redemptive work of Christ, who bore our sins and provided a means of restoration for all who believe in Him. God showcases His capacity to heal spiritually and physically through these illustrations.
