LBCF 8-1 gives us the covenantal context for Christ as the Mediator. In the Covenant of Redemption, God the Son, namely Jesus Christ, was appointed by God the Father in eternity to be the mediator between God and Man. The Father promises to send the Spirit to aid him as Mediator and to give him a special seed who would be redeemed, called, justified, sanctified, and glorified.
