I will put my laws into their mind, and write them in their hearts: and I will be to them a God, and they shall be to me a people. Hebrews 8:4-10 (KJV)
Old Testament worship pointed towards the heaven. The rituals referred to higher realities. With Christ, there is a fulfilment of the OT that transcends impersonal transactions through the Law. He fixes our desires. Israel repeated fail the old covenant because it is not in our natural desires to worship God. The new covenant is personal. It is initiated with an internal transformation. Worship is not performative. It becomes the character of a new identity. The advent is a wonderful reminder of this blessed state, this affordance to actual desire God and godliness in our lives.
