What does Malachi 3:15 mean?
Malachi 2:17 presented a dangerous, hypocritical complaint against God. Namely, that He was not sufficiently punishing the wicked. God's response, in the earlier verses of chapter 3, was to warn Israel that judgment was, in fact, coming. And it was coming to Israel first. Verses 13 and 14 detailed one of Malachi's final accusations against Israel, which is that of blasphemy: speaking "harsh" words against God. These, and the attack here in verse 15, are similar to the criticisms of Malachi 2:17. Part of the suggestion being made is that God is not holding up His end of their covenant agreement.Of course, the fact that God keeps His promises is the only reason Israel has survived long enough to make this complaint in the first place (Malachi 3:6). Neither the people, nor the priests, are obeying the commands of God (Malachi 1:7–8; 2:11–14; 3:8).
Israel has already been reminded that God has punished evil in the past (Malachi 1:2–5). He will purify His people at some point in the future (Malachi 3:2–4). And, according to the warning coming at the beginning of chapter 4, this judgment will be all-encompassing (Malachi 4:1).
