The people in Jerusalem are just as corrupt as their ancestors who returned from exile 100 years ago. Malachi confronts their sins, pointing out that Israel cannot be faithful to the covenant God made with them. Yet God will not abandon His people, and promises a Messiah to the remnant who are still faithful to Him. This is the last Israel will hear from God, and 400 years will pass before the appearance of John the Baptist announcing the coming of Jesus.
