There will be great trouble [during these times], such as had never been from the beginning of time up to the present, or ever will be [in the days to come].

Matthew 24:29

"But immediately after the terrible trouble of those days, [i.e., the next major event on God's calendar], the sun will become dark, and [therefore] the moon will not [be able to] shed its [reflected] light. The stars will fall from the sky and the forces of the heavens will be shaken [Note: From the description of these same events in Luke 21:25-26, it is possible that this is figurative language for great calamities happening on the earth].

Mark 13:9

"But pay attention to yourselves, for people will turn you over to [Jewish] councils [i.e., for judgment] and you will be beaten in synagogues. You will stand trial before governors and kings for being loyal to me. [This will afford you an opportunity] for witnessing to them.

Luke 21:24

And people will die by the sword and be led captive into all nations. And Jerusalem will be trampled on by the [unconverted] Gentiles [i.e., by the Romans and later by others] until the times of [domination by] the Gentiles are fulfilled.

1 Thessalonians 2:16

for they [even] try to prevent us from speaking to the Gentiles, so that they can be saved. [In doing this] they are always piling up one sin on another. But the wrath [of God] has come upon them at last [or, "completely"].

Hebrews 10:26-29

For if we go on sinning intentionally, after we have received the full knowledge of the truth, there is no longer any sacrifice for [our] sins.
