New Defender's Study Bible Notes
1:15 day of the LORD. “The day of the LORD,” in contrast to “man’s day,” refers to a coming time of judgment. The Lord will take strong control of the world and its inhabitants in severe judgment, after a long time of patient forbearance. This will be followed by cleansing and blessing. Such prophecies often refer to a current situation, such as the plague of locusts, then leap over the centuries to the future end-time judgments, the former being a type of the latter. Sometimes it refers to the entire period of judgment, sometimes to the specific day on which that period will begin. In the prophets, it occurs first in Isaiah 2:12, last in Malachi 4:5. There are other phrases that are used synonymously—“the day of wrath,” “the day of God,” “that day,” etc.
