This week we explore the purification offering of the sanctuary system. This offering was also known as the sin offering. What was the purpose of this offering? How does it illustrate the way in which God deals with man? What did it teach the Israelites about how God removes sin from the sinner? We also explore three categories of sin: unintentional sin, deliberate sin, and rebellion. The substitutionary nature of the sacrificial system is explored as we delve into this topic.
