The Messenger of the Covenant
In Malachi chapter 3:1, God introduces us to the Messenger of the New Covenant in whom we delight. This covenant was a greater covenant than that which had been handed-down to the Levites in laws and stories, but which they strayed away from. This new covenant would be about personal relationship with the Messenger of the Covenant and would solve the sin problem once and for all.
This passage covers both the first advent of Christ as the Messiah, the Savior of the world, and the second coming—which we believe is very soon to happen, when Jesus will sit in judgment as the refiner and purifier. His first coming forces people to decide what to do about God. The second coming will bring judgment and justice to those who reject it, and eternal blessing to those who hear it and accept it. The question is, have you heard and accepted His salvation plan?
