The following is from Thomas Brooks, and a message entitled Touchstone of Sincerity.
The terms upon which Christ is offered in the gospel are these: that we shall accept of a whole Christ with a whole heart. Now, mark--a whole Christ includes all His offices; and a whole heart includes all our faculties.
Christ as mediator is prophet, priest, and king.
Christ as a prophet instructs us.
Christ as a priest redeems us and intercedes for us.
Christ as a king sanctifies and rules us.
A hypocrite may be willing to embrace Christ as a priest to save him from wrath, from the curse, from hell, from everlasting burning--but he is never sincerely willing to embrace Christ as a prophet to teach and instruct him, and as a king to rule and reign over him. Many hypocrites are willing to embrace a saving Christ--but they are not willing to embrace a ruling Christ, a commanding Christ. "But those mine enemies, which would not that I should reign over them, bring hither, and slay them before me." Luke 19:27
Hypocrites love to share with Christ in His happiness--but they don't love to share with Christ in His holiness.
They are willing to be redeemed by Christ--but they are not cordially willing to submit to the laws and government of Christ.
They are willing to be saved by His blood--but they are not willing to submit to His scepter.
But a true Christian receives Christ in all His offices. He accepts Him, not only as a saving Jesus--but also as a Lord Jesus. He embraces Him, not only as a saving Christ--but also as a ruling Christ. He received Christ as a king upon His throne, as well as an atoning sacrifice upon His cross.A hypocrite is all for a saving Christ, for a sin-pardoning Christ, for a soul-saving Christ--but has no regard for a ruling Christ, a reigning Christ, a commanding Christ, a sanctifying Christ;and this at last will prove his damning sin.
