What does the Bible say about approaching God without a mediator?

According to 2 Chronicles 26, King Uzziah made the grave mistake of approaching God without a mediator. The text illustrates that to come before God without an advocate is to risk divine judgment and punishment. Uzziah, despite his earthly success, presumed upon God's grace and entered the temple to burn incense without the prescribed priestly mediation. The consequences of his actions were severe, as exemplified when leprosy broke out upon him as a sign of God’s displeasure. The necessity of a mediator is foundational in historic Reformed theology, illustrating our absolute dependence on Christ, who intercedes for us. Hebrews 4:14 emphasizes that we have a great High Priest—Jesus, the Son of God—who represents us before the Father.
