Behold, I will send my messenger, and he shall prepare the way before me: and the LORD, whom you seek…
This passage cannot speak of any intervention of the Deity, like that which the nation of Israel had often experienced; here was a prediction of the Messiah to come. His Divine nature is declared, and yet, when He is spoken of as the Messenger of the Almighty, we see Him as distinct from God in His human nature. He is the Lord who should come to His own temple; and He is the Messenger or Servant of the Lord of hosts. He is not the Messenger of the Mosaic covenant. That had long previously been established under Moses, as its mediator. Isaiah writes of another covenant, an "everlasting covenant." The national covenant must pass to give way to a better. Of this new covenant, to receive the elect remnant of the Jews, and to gather around them all the elect people of the Gentiles — of this covenant it is here said, that the Messiah to come was to be the Messenger; He should establish the covenant; He should be its source; He should be its Mediator; He should be the very substance of the covenant. It was His blood formed that covenant; when He made an atonement for transgression He rendered it possible, because it became just and right that the Almighty should again enter into a covenant of peace with His rebellious creatures. Look at Christ under this character, the "Messenger of the covenant," — Him who was sent of God to establish and confirm it. He, in order to bring His people into covenant with God, has been their substitute in suffering. He would also secure us every best blessing. He has become our wisdom, He has also become our sanctification. He is also our perfect example. He becomes an advocate for each of His offending people. And He is our High Priest, touched with the feeling of our infirmities. The prophet tells of the reception which the Saviour was to meet. "Whom ye delight in." And good reason have we to delight in this Messenger of the covenant, if indeed we have tasted of His love. We may delight in what He has done, what He does, and what He will do for us.
