The Day of the Lord is a future event where God will pour out his wrath on the earth. The plagues that God sends during this time will be unlike anything that’s ever happened or will ever happen again. It will be a time of punishment both for the world and for those of God’s people who have turned their backs on Him. God has not destined us for wrath, so let’s live for Him and put behind us the sins because of which this time of judgment is coming.
