Malachi 1:1–5 introduces this prophecy as one from Malachi, meaning ”My Messenger.” This passage summarizes the basic spiritual problem facing Israel: apathy. God has shown His love for them, but they don’t recognize it anymore. To show how He has loved them, Malachi points to the destruction of Edom. Israel has suffered, but God has kept them through those struggles. Edom, on the other hand, has been obliterated. God’s chosen people have sinned, but they haven’t been destroyed, which is an act of God’s love and mercy towards them.
