How do we know Moses was a mediator before Christ?

Moses served as a mediator between God and the people of Israel, especially when they expressed fear of God's direct presence. In Deuteronomy, the Israelites implored Moses to speak to God on their behalf, recognizing their inability to stand before His holiness (Deuteronomy 5:23-27). This mediatorial role is significant; it established a precedent for the future mediator, Jesus Christ. As the New Testament states, there is one mediator between God and man, Christ Jesus (1 Timothy 2:5), fulfilling and surpassing Moses' role. Christ, as our mediator, not only speaks on our behalf but also offers Himself as the sacrifice, making reconciliation possible through His blood.
