Paul, Silvanus, and Timothy,
To the church of the Thessalonians in God the Father and the Lord Jesus Christ:
Grace to you and peace.
 We give thanks to God always for all of you, constantly mentioning you in our prayers,  remembering before our God and Father your work of faith and labor of love and steadfastness of hope in our Lord Jesus Christ.  For we know, brothers loved by God, that he has chosen you,  because our gospel came to you not only in word, but also in power and in the Holy Spirit and with full conviction. You know what kind of men we proved to be among you for your sake.  And you became imitators of us and of the Lord, for you received the word in much affliction, with the joy of the Holy Spirit,  so that you became an example to all the believers in Macedonia and in Achaia.  For not only has the word of the Lord sounded forth from you in Macedonia and Achaia, but your faith in God has gone forth everywhere, so that we need not say anything.  For they themselves report concerning us the kind of reception we had among you, and how you turned to God from idols to serve the living and true God,  and to wait for his Son from heaven, whom he raised from the dead, Jesus who delivers us from the wrath to come.
(1 Thessalonians 1 ESV)
 “But when you see Jerusalem surrounded by armies, then know that its desolation has come near.  Then let those who are in Judea flee to the mountains, and let those who are inside the city depart, and let not those who are out in the country enter it,  for these are days of vengeance, to fulfill all that is written.  Alas for women who are pregnant and for those who are nursing infants in those days! For there will be great distress upon the earth and wrath against this people.  They will fall by the edge of the sword and be led captive among all nations, and Jerusalem will be trampled underfoot by the Gentiles, until the times of the Gentiles are fulfilled.
 “And there will be signs in sun and moon and stars, and on the earth distress of nations in perplexity because of the roaring of the sea and the waves,  people fainting with fear and with foreboding of what is coming on the world. For the powers of the heavens will be shaken.  And then they will see the Son of Man coming in a cloud with power and great glory.  Now when these things begin to take place, straighten up and raise your heads, because your redemption is drawing near.”
 And he told them a parable: “Look at the fig tree, and all the trees.  As soon as they come out in leaf, you see for yourselves and know that the summer is already near.  So also, when you see these things taking place, you know that the kingdom of God is near.  Truly, I say to you, this generation will not pass away until all has taken place.  Heaven and earth will pass away, but my words will not pass away.
 “But watch yourselves lest your hearts be weighed down with dissipation and drunkenness and cares of this life, and that day come upon you suddenly like a trap.  For it will come upon all who dwell on the face of the whole earth.  But stay awake at all times, praying that you may have strength to escape all these things that are going to take place, and to stand before the Son of Man.”
(Luke 21:20-36 ESV)
