Malachi's Seven Disputs - I've Loved You

A theme that's mentioned often is this, if you return to me, I will return to you. The people have broken their covenants and God will not give them the blessings if they're just going through the motions. Tithing is another theme here because he's stressing the need to care for the poor. And then the beautiful prophecies that are fulfilled both in Malachi's time and the Savior's first and second coming.
