Matthew 24: 21-22
21 For then shall be great TRIBULATION, such as was not since the beginning of the world to this time(this current time), no, nor ever shall be.
22 And except those days should be shortened, there should no flesh be saved: but for the elect's sake those days shall be shortened.
Isaiah 26:20-21
20 Come, my people, enter thou into thy chambers, and shut thy doors about thee: hide thyself as it were for a little moment (seven years), until the indignation be overpast.
21 For, behold, the Lord cometh out of his place to punish the inhabitants of the earth for their iniquity: the earth also shall disclose her blood, and shall no more cover her slain.
Romans 2:6-11
6 GOD will render to every MAN according to his deeds:
7 To them who by patient continuance in well doing seek for glory and honour and immortality, eternal life:
8 But unto them that are contentious, and do not obey the truth, but obey unrighteousness, indignation and wrath,
9 Tribulation and anguish, upon every soul of man that doeth evil, of the Jew first, and also of the Gentile;
10 But glory, honour, and peace, to every man that worketh good, to the Jew first, and also to the Gentile:
11 For there is no respect of persons with GOD.
Revelation 11:15 and 18
15 ... The kingdoms OF THIS WORLD are become the kingdoms of our Lord, and of his Christ; and he shall reign for ever and ever.
18 And the nations were(will be)angry, and thy wrath is come, and the time of the dead, that they should be Judged(Daniel 12:2. Take a look), and that thou should give reward unto thy servants the prophets, and to the saints, and them that fear thy name, small and great; and should destroy them which destroy the earth.

To compare, here's two similar terrible situations
Psalm 34:19-Many are the afflictions of the righteous:but the Lord delivers him out of them all.
Acts 14:22-We must through much tribulation enter into the Kingdom of GOD.
The KING of DARKNESS,the Devil,showed to JESUS all the kingdoms of the world,the glory of them,and said:All will I give thee,if thou fall down and worship me.Mat.4:8-9.
Re.13:1&15:
1 I stood upon the sand of the sea(John was a citzen of Israel),and saw a(MAN)Beast rise up out of the sea(Gentile nations),having 7 heads,10 horns,upon his HORNS 10 crowns,and upon his heads a NAME of blasphemy.
15And he-MAN Beast of earth-Re.13:11-a false messiah-John 5:43-47,had power to give life unto the Beast's image,that the image should speak,who worships not the image must be killed.
Daniel 3:2-20
The KING sent to gather the princes,governors,the captains,the judges,the counsellors,all the rulers of the provinces,to come to the dedication of the image he had set up.They stood before the image and an herald cried:To you is commanded,O people,NATIONS,and languages,that at what time ye hear the sound of the cornet,flute, harp,and all kinds of musick,ye fall down and worship the image the king has set up:Whoso falls not down and worships shall be cast into the burning fiery furnace.But Shadrach,Meshach,Abednego,O king,have not regarded thee,they serve not thy gods,nor worship the image you has set up.So in his rage and fury the KING commanded to bring them,and said:Is it true,O Shadrach,Meshach,Abednego,do not ye serve my gods,nor worship the IMAGE I have set up?When you hear the sound of the cornet,flute,harp,psaltery,and all kinds of musick,ye fall down and worship the image I have made;well: if not,ye shall be cast into the midst of a burning fiery furnace;who is that GOD that shall deliver you out of my hands?
O king,our GOD whom we serve is able to deliver us from furnace,thy hands,and we will not serve thy gods,nor worship the image you have set up .
