The Christ, Prophet
The Larger Catechism of the Westminster Standards teaches us of Christ or Mediator who is our Prophet.
Q. 42. Why was our Mediator called Christ?
A. Our Mediator was called Christ, because he was anointed with the Holy Ghost above measure, and so set apart, and fully furnished with all authority and ability, to execute the offices of prophet, priest, and king of his church, in the estate both of his humiliation and exaltation.
Q. 43. How doth Christ execute the office of a prophet?
A. Christ executeth the office of a prophet, in his revealing to the church, in all ages, by his Spirit and Word, in divers ways of administration, the whole will of God, in all things concerning their edification and salvation.
Every person lies, sits and stands in need of edification. To edify is to improve by instruction. Instruction is by encouragement, exhortation or teaching.
Everyone exists in the 'theater of God' each day. But the expression of the fallen man in that theater is to praise the theater rather than the Operator and Owner of the theater. Therefore, God sent his Mediator, Jesus, to save his people from their sins. This Mediator is the anointed one of God who speaks to those he came to save, his church. He is her Prophet to instruct his people, his bride, his family, his household, concerning her salvation, and to edify her in that salvation.
Everyday he is the One speaking for his church to be built up into him as her salvation. The Father spoke from heaven to the disciples on the mountain saying, "This is my Son. Listen to him". We must listen to him speak as he edifies us from where we lie, sit and stand that we may live in him who is our salvation.
