Jesus will not leave everything the way it is.
He will come back to judge the
world in righteousness.

This is a short intermission in the relatively short history of our present heavens and earth, and a short time of amnesty from all of our wrongs, before Jesus brings this disintegrating universe to a close. Jesus now has all authority in both heaven and earth, Mtt 28:18. He is now working to put down all opposition.

“25 For he must reign until he has put all his enemies under his feet. 26 The last enemy that will be abolished is death.”
1Cor 15:25-26

Jesus has given us a ministry of reconciliation, 2Cor 5:19.

This short time just before Jesus comes again, is time for us to repent, and come to our senses.

“The Lord is not slow concerning his promise, as some count slowness; but is patient with US, not wishing that any should perish, but that all should come to repentance.”
2Pe 3:9

Jesus promises us that terrible things will happen,
just before the end of our age.

Paul speaks of these things in a general sense in his letter to Timothy.

“But the Spirit says expressly that in later times some will fall away from the faith, paying attention to seducing spirits and doctrines of demons”
1Tim 4:1

“But know this, that in the last days, grievous times will come.”
2Tim 3:1

The details are given in both the Old and the New Testaments. A war will come by “the little horn,” “the abomination of desolation,” the living corpse, “the man of lawlessness,” “the beast,” against all righteousness and goodness and holiness in the entire world.

Jesus will bring all of mankind’s, and the spirit world’s, foolishness,
to a dramatic close.

Moses tells us both when the Jews will turn to Jesus of Nazareth, and when Jesus will come again.

“For Yahweh will judge his people,
Repent himself for his servants;
When he sees that their power is gone,
There is none remaining, shut up or left at large.”
Deut 32:36

When all is lost and there is no hope, and strength to oppose evil, THEN Jesus will come

“25 There will be signs in the sun, moon, and stars; and on the earth anxiety of nations, in perplexity for the roaring of the sea and the waves; 26 men fainting for fear, and for expectation of the things which are coming on the world: for the powers of the heavens will be shaken. 27 Then they will see the Son of Man coming in a cloud with power and great glory. 28 But when these things begin to happen, look up, and lift up your heads, because your redemption is near.”
Lk 21:25-28

Prophecy is pertinent to our lives throughout all history. We are truly on the edge of forever.

If you believe this, you will try to be ready for this. It will change how you live, it will change your ethics. Prophecy is NOT an optional extra. Believing what God says in prophecy does matter! It is an ethical matter.
