Christ, and Christ alone, is fitted to be mediator between God and man. He is the prophet, priest and king of the church of God. His office as mediator cannot be transferred from Him to any other, either in whole or in part. Paragraph 9

1. Because of our ignorance
2. Because of our estrangement from God and the imperfection of our services at their best
3. Because we have turned away from God and are utterly unable to return to Him
4. Because we need to be rescued and rendered secure from our spiritual adversaries

1. By His prophetical office he teaches us the truth of our need and God's gracious provision, uniquely revealing God to us.
2. By His priestly office he reconciles us to God and renders us acceptable to Him
3. By His kingly office he convinces, subdues, draws, sustains, delivers and preserves us, until we finally enter His heavenly kingdom.
