Psalm 9:17 says, "The wicked shall be turned into hell, and all the nations that forget God." Why?

Paul explains:

{F}or revealed is the wrath of God from heaven upon all impiety and unrighteousness of men, holding down the truth in unrighteousness. Because that which is known of God is manifest among them, for God did manifest [it] to them, for the invisible things of Him from the creation of the world, by the things made being understood, are plainly seen, both His eternal power and Godhead -- to their being inexcusable; because, having known God they did not glorify [Him] as God, nor gave thanks, but were made vain in their reasonings, and their unintelligent heart was darkened, professing to be wise, they were made fools, and changed the glory of the incorruptible God into the likeness of an image of corruptible man, and of fowls, and of quadrupeds, and of reptiles. Wherefore also God did give them up, in the desires of their hearts, to uncleanness, to dishonour their bodies among themselves; who did change the truth of God into a falsehood, and did honour and serve the creature rather than the Creator, who is blessed to the ages. Amen.

"Because of this did God give them up to dishonourable affections, for even their females did change the natural use into that against nature; and in like manner also the males having left the natural use of the female, did burn in their longing toward one another; males with males working shame, and the recompense of their error that was fit, in themselves receiving. And, according as they did not approve of having God in knowledge, God gave them up to a disapproved mind, to do the things not seemly; having been filled with all unrighteousness, whoredom, wickedness, covetousness, malice; full of envy, murder, strife, deceit, evil dispositions; whisperers, evil-speakers, God-haters, insulting, proud, boasters, inventors of evil things, disobedient to parents, unintelligent, faithless, without natural affection, implacable, unmerciful; who the righteous judgment of God having known -- that those practising such things are worthy of death -- not only do them, but also have delight with those practising them.

Jesus said:

For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. For God sent not his Son into the world to condemn the world; but that the world through him might be saved. He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God. And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil. For every one that doeth evil hateth the light, neither cometh to the light, lest his deeds should be reproved.

God said to Ezekiel that He takes no pleasure in the death of the wicked (Ezekiel 33:11). However, Jesus spoke more about Hell than He did about Heaven while He was here on earth. And He described it vividly:

And if thy hand offend thee, cut it off: it is better for thee to enter into life maimed, than having two hands to go into hell, into the fire that never shall be quenched: Where their worm dieth not, and the fire is not quenched. And if thy foot offend thee, cut it off: it is better for thee to enter halt into life, than having two feet to be cast into hell, into the fire that never shall be quenched: Where their worm dieth not, and the fire is not quenched. And if thine eye offend thee, pluck it out: it is better for thee to enter into the kingdom of God with one eye, than having two eyes to be cast into hell fire: Where their worm dieth not, and the fire is not quenched.

My friends, there are people all around you who don't know about this, because Satan wants to focus them on the pleasures of sin and not the penalty for it. Telling them that Jesus will make your life better is not revealing to them the whole truth. You who are saved should have peace knowing that your sins are forgiven and that you will not come to this place--but what about those that haven't repented and haven't surrendered to Jesus? This is what awaits them. Do you love your neighbors or not?

Then tell them the Truth:

"Hell is hot, and sin ain't right!/And God is Holy and Christ is coming/And Righteousness will prevail!" ~Carman, "Radically Saved"
