How does proper worship relate to understanding the Gospel?

The discrepancies in worship displayed by David and the Israelite leaders reveal that true worship cannot exist without acknowledging the role of Jesus Christ, the ultimate High Priest. In the Old Testament, the Ark represented God's presence, and in the New Testament, Christ fulfills that representation, as our mediator. The blood of Christ is vital in our worship as it signifies the only way to approach God. Worship, therefore, must always include a clear presentation of the Gospel, where the blood and sacrifice of Jesus are central, reaffirming that we can have no communion with God apart from Him.
