What does the Bible say about God's judgment and plagues?

In the Bible, especially in books like Zechariah and Exodus, plagues serve as symbols of God's judgment on sin and disobedience. Zechariah 14:12 explicitly discusses a plague the Lord will send, serving as a solemn reminder of the consequences faced by those who reject God's grace. Throughout scripture, God's use of plagues demonstrates His sovereignty and authority over creation, acting as both a punishment for sin and a call to repentance. The plagues symbolize the spiritual decay brought on by sin, where those who are unresponsive to God's grace face severe repercussions, underlining the vital importance of acknowledging and accepting God's mercy.
