God Throws All Sinners In The Lake Of Fire

40 Just as the weeds are gathered and burned with fire, so will it be at the end of the age. 41 The Son of Man will send his angels, and they will gather out of his kingdom all causes of sin and all law-breakers, 42 and throw them into the fiery furnace. In that place there will be weeping and gnashing of teeth. 
Matthew 13:40-42 (ESV)

14 Then Death and Hades were thrown into the lake of fire. This is the second death, the lake of fire. 15 And if anyone’s name was not found written in the book of life, he was thrown into the lake of fire.
Revelation 20:14-15 (ESV)

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.”
Revelation 21:8 (ESV)

God Will Punish With Everlasting Punishment (Hell)

 since indeed God considers it just to repay with affliction those who afflict you, and to grant relief to you who are afflicted as well as to us, when the Lord Jesus is revealed from heaven with his mighty angels in flaming fire, inflicting vengeance on those who do not know God and on those who do not obey the gospel of our Lord Jesus. They will suffer the punishment of eternal destruction, away from the presence of the Lord and from the glory of his might, 10 when he comes on that day to be glorified in his saints, and to be marveled at among all who have believed, because our testimony to you was believed.
2 Thessalonians 1:6-10 (ESV)

Vengeance Is God’s, The Lord Will Repay, Jesus Will Judge You

5But because of your hard and impenitent heart you are storing up wrath for yourself on the day of wrath when God’s righteous judgment will be revealed.
He will render to each one according to his works: to those who by patience in well-doing seek for glory and honor and immortality, he will give eternal life; but for those who are self-seeking and do not obey the truth, but obey unrighteousness, there will be wrath and fury. 

Romans 2:5-8 (ESV)

30 For we know him who said, “Vengeance is mine; I will repay.” And again, “The Lord will judge his people.” 
Hebrews 10:30 (ESV)

God Observes Everything In Silence

3 The eyes of the Lord are in every place,
keeping watch on the evil and the good.

Proverbs 15:3 (ESV)

knowing this first of all, that scoffers will come in the last days with scoffing, following their own sinful desires. They will say, “Where is the promise of his coming? For ever since the fathers fell asleep, all things are continuing as they were from the beginning of creation.”
2 Peter 3:3-4 (ESV)
