Why is the sacrifice of Christ central to worship?

The sacrificial death of Christ is the linchpin of Reformed worship theology. It is through His blood, as articulated in Hebrews 9:12, that we are granted eternal redemption. This redemptive act not only fulfills the requirements of the law but also highlights that all worship must be centered around His work — not ours. Any attempts to approach God through our own righteousness or works are seen as futile and defiling, similar to how Uzzah's error in trying to stabilize the Ark resulted in death. Recognizing that our worship must be saturated in Christ's atoning sacrifice ensures it is biblically grounded and pleasing to God.
