Exodus 25, 26
/Exodus 25 begins the detailing of the plans for the Ark of the Covenant, (25:22) a place where God would meet with Moses. The ark held the testimony of the Law. On top of the ark was the mercy seat (v21). Annually the high priest would sprinkle the blood on the mercy seat to symbolically atone for the sins of Israel.
The blood of Christ is not symbolic. It really cleanses (Heb 9:11-14; 10:8-10). His invitation to us is to “come boldly to a throne of grace (3:14-16). He will still meet us there.
