What role does the mercy seat play in Christ being our hiding place?

The mercy seat, found in the Holy of Holies, is where the high priest sprinkled the blood of the lamb for atonement. This foreshadows Christ's ultimate sacrifice, as described in Hebrews 9:12, which states that He entered once for all into the holy places, securing an eternal redemption. In this way, the mercy seat represents the intersection of God's justice and mercy through Christ. Thus, our assurance of being hidden from God's wrath lies in His completed atonement for our sins, confirming that He is our refuge.
