Existence of hell
(Verses 11 and 24 in Chapter 15 of Proverbs are clubbed together).
Hell and destruction are before the LORD: how much more then the hearts of the children of men? (Proverbs 15:11)
The Lord had not created the hell originally as He created that was good. But the devil forsook the Heaven and fell down and God had to make a place for the devil and the angels who sinned against God. The devil is reigning this place and is taking the souls into this place.
The hearts of men should fear and know the truth about hell and destruction. Evangelists have to preach about hell and destruction.
The way of life is above to the wise, that he may depart from hell beneath (Proverbs 15:24).
The way of life is shown by the wise to those who are on the way to perdition. It is the gospel of Christ that saves the mankind from the hell. Preachers of gospel are the wise who impart eternal life to those who are dead in sin.
