What does it profit a man if he gains the whole world but loses his own soul? Mark 8:36

And if your eye causes you to sin, pluck it out. It is better for you to enter the kingdom of God with one eye, rather than having two eyes, to be cast into hell fire - where their worm does not die and the fire is not quenched. Mark 9:47

For if God did not spare the angels who sinned but cast them down to hell and delivered them into the chains of darkness, to be reserved for judgement... 2 Peter: 2:4

Do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived. Neither fornicators, nor idolaters, nor adulterers, nor homosexuals, nor sodomites, nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners will inherit the kingdom of God. 1 Corinthians 6:9-10  

But the cowardly, the unbelieving, the vile, the murderers, the sexually immoral, those who practice magic arts, the idolaters and all liars - they will all be consigned to the fiery lake of burning sulphur. This is the second death. Revelations 21:8
