There is a hell to be avoided

“And these will go away into eternal punishment, but the righteous into eternal life.” (Matt. 25:26 ESV)

Who will be in hell?

“But as for the cowardly, the faithless, the detestable, as for murderers, the sexually immoral, sorcerers, idolaters, and all liars, their portion will be in the lake that burns with fire and sulfur, which is the second death.” (Rev. 21:8 ESV)

“And the sea gave up the dead which were in it, and death and Hades gave up the dead which were in them; and they were judged, every one of them according to their deeds. Then death and Hades were thrown into the lake of fire This is the second death, the lake of fire. And if anyone's name was not found written in the book of life, he was thrown into the lake of fire.” (Rev. 20:13-15)

“Then he will say to those on his left, ‘Depart from me, you cursed, into the eternal fire prepared for the devil and his angels.” (Matt. 25:41 ESV)

“And the devil who deceived them was thrown into the lake of fire and brimstone, where the beast and the false prophet are also; and they will be tormented day and night forever and ever.” (Rev. 20:10)

Therefore…

“And do not fear those who kill the body but cannot kill the soul. Rather fear him who can destroy both soul and body in hell.” (Matt. 10:28 ESV)

“Enter through the narrow gate; for the gate is wide and the way is broad that leads to destruction, and there are many who enter through it.” (Matt. 7:13)

Saved from hell by Jesus

“For the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord.” (Rom. 6:23 ESV)

“For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life. For God did not send his Son into the world to condemn the world, but in order that the world might be saved through him. Whoever believes in him is not condemned, but whoever does not believe is condemned already, because he has not believed in the name of the only Son of God.” (John 3:16-17 ESV)
