Concerning His mediatorship, the Scripture holds forth Christ's call to His office; for none takes this honor upon Him, but He that is called of God as was Aaron, it being an action of God, whereby a special promise being made, He ordains His Son to this office; which promise is, that Christ should be made a sacrifice for sin; that He should see His seed, and prolong His days, and the pleasure of the Lord shall prosper in His hand; all of meer free and absolute grace towards God's elect, and without any condition foreseen in them to procure it.
Heb. 5:4,5,6, Isa. 53:10,11; John 3:16; Rom. 8:32.
