Lo, the day is coming, blazing like an oven, when all the proud and all evildoers will be stubble, and the day that is coming will set them on fire, leaving them neither root nor branch,
says the LORD of hosts. But for you who fear my name, there will arise the sun of justice with its healing rays. (Mal 3:19-20a)

The Bible does speak of the Day of the Lord, but too often people focus on fire “blazing like an oven” rather than on the message of salvation—the “sun of justice with its healing rays.” Maybe for good reason the Lord cautions us: "See that you not be deceived, for many will come in my name, saying, 'I am he,' and 'The time has come.' Do not follow them!”
