Matthew 13

Malachi warned -

"...the day cometh, that shall burn as an oven; and all the proud, yea, and all that do wickedly, shall be stubble: and the day that cometh shall burn them up..." (Old Testament | Malachi 4:1)

We see this same teaching in parable as the Lord taught -

"...the kingdom of heaven is like unto a net, that was cast into the sea, and gathered of every kind:
48 Which, when it was full, they drew to shore, and sat down, and gathered the good into vessels, but cast the bad away." (New Testament | Matthew 13:47 - 48)

How will this be done?

"...at the end of the world: the angels shall come forth, and sever the wicked from among the just,
50 And shall cast them into the furnace of fire..." (New Testament | Matthew 13:49 - 50)

I believe that day will come.
