How the Bible explain Hebrews 10:10

**Hebrews 10:10** states: *"And by that will, we have been made holy through the sacrifice of the body of Jesus Christ once for all."* The verse explains that believers are **sanctified (made holy)** not through repeated animal sacrifices under the Mosaic Law, but through the **single, sufficient sacrifice of Jesus Christ**. The phrase "once for all" (*ephapax* in Greek) emphasizes the finality and completeness of Christ's atoning work — it never needs to be repeated. This contrasts with the Old Testament priestly system, where sacrifices were offered continually (Hebrews 10:1-3). The "will" referenced is God's redemptive plan, fulfilled through Christ's obedience and death, which permanently secures the believer's standing before God.
