What does the Bible say about entering the presence of God?

According to Hebrews 10:19-20, believers have the boldness to enter into the holy of holies through the blood of Jesus Christ. This represents a new and living way that He has consecrated for us. Unlike the old covenant priests who entered with fear and the blood of animals, believers can approach God confidently because their sins are forgiven, and they are accepted due to Christ's perfect sacrifice. This access is not about our works; it is based solely on the efficacy of Christ's blood.
