What does the Bible say about entering the holiest by the blood of Jesus?

Hebrews 10:19-22 explains that due to Christ's sacrifice, believers can confidently enter the holiest presence of God. The veil that once separated God from the people has been torn, symbolizing access granted through Jesus’ flesh. This passage emphasizes the significance of Christ's sacrifice, which alone sanctifies us and allows us to approach God without fear. Believers are encouraged to draw near with a true heart in full assurance of faith, having received cleansing from sin through Christ’s atoning blood.
