Like all the writing prophets, Malachi's chief revelation was the person and work of Yahweh. He presented Israel's God as sovereign over Israel and the whole world and as very patient with His wayward people.
Malachi also used the Mosaic Covenant as the ruler by which he measured Israel's conduct. He pointed out instances of covenant unfaithfulness and urged return to the covenant. He also reminded the Israelites of Yahweh's faithfulness to His covenant promises including promises of future blessing. Thus he sought to motivate his hearers to return to the Lord by convicting them of their sins and converting them to love for their Savior.
His notable messianic prophecy deals with His forerunner (3:1; 4:5). He would be like Elijah and would call the Israelites to repentance (cf. Matt. 11:14; 17:12-13; Mark 9:11-13; Luke 1:17).
