How do we know Jesus Christ is the mercy seat?

Jesus Christ is referred to as the mercy seat in the context of the tabernacle and the sacrificial system established in the Old Testament. The mercy seat, located on the Ark of the Covenant, was where the high priest sprinkled the blood of a sacrifice to atone for the sins of the people. In this way, it represents God's mercy and grace. Christ, fulfilling the role of high priest and sacrificial lamb, provides ultimate atonement through His own blood, making Him the true mercy seat where sinners can find forgiveness and reconciliation with God.
