The 7 feasts of Israel are prophetic in nature, typifying the coming of the Messiah. They demonstrate both the holiness of God and the sinfulness of humanity. There are three types of laws in the Old Testament - moral laws that show humanity's sin, civil laws regarding Israel's government, and ceremonial laws that foreshadow fulfillment in Christ. The feasts together depict how Christ sacrificed himself so that believers may have forgiveness and eternal life.
