As Malachi reaches the climax of his book and the conclusion of the Old Testament, he pushes home the issue of a right knowledge of God and all that flows from it.--On the one hand, he describes the faithless, who bring hard accusations against God, and conclude that it is pointless to serve him. On the other, he describes the faithful, who are revealed in terms of their attitude -they fear the Lord-, their speech -they talk to one another, presumably words of faith and truth-, their witness -the Lord taking note of their activity-, and their confidence -that they will be spared when judgment comes-.--In that day, the character of God will be gloriously revealed, and the confidence of his saints fully vindicated.
