After leading with His faithful, covenantal love for His people in the first 5 verse of Malachi, now Yahweh God brings forth the many different ways that they are being unfaithful to Him. He starts with the priests and the fact that they dishonor Him by not teaching truth to the people as they should and offering blemished animals as sacrifices to Him. (which the people bring). He presents Levi as an example of a faithful priest who points us to Christ. Today, the Church needs faithful pastors who teach Bible and present Christ as the answer. Jesus Himself is the Faithful Priest who taught truth, offered the perfect, unblemished sacrifice for sin, which was His own body.
