The relationship between the Old and New Covenants parallels the relationship between an actual historical event and a stage play or film scripted to remember it. In the Old Covenant, the tabernacle and Temple were the stages, the furniture the props, the priests the actors. But what made their work unique is that they weren’t portraying something that had happened already but something that was going to happen. God in His wisdom was giving them a preview of the great event that would transform human history.
