What does the Bible say about the importance of an advocate between man and God?

The book of Job highlights our need for a mediator through Job's own words in Job 9:33, which expresses the absolute necessity for someone to stand between us and God. This aligns with the New Testament teaching that Jesus Christ is our advocate with the Father, as seen in 1 John 2:1. Without this divine mediator, we cannot bridge the gap created by our sin against a holy God. It is essential for Christians to understand that our relationship with God relies on the work of Christ, who alone can intercede and restore our broken fellowship with Him.
