1Paul, Silvanus, and Timothy, to the assembly of the Thessalonians in God the Father and the Lord Jesus Christ: Grace to you and peace from God our Father and the Lord Jesus Christ.
2We always give thanks to God for all of you, mentioning you in our prayers, 3remembering without ceasing your work of faith and labor of love and perseverance of hope in our Lord Jesus Christ, before our God and Father. 4We know, brothers loved by God, that you are chosen, 5and that our Good News came to you not in word only, but also in power, and in the Holy Spirit and with much assurance. You know what kind of men we showed ourselves to be among you for your sake. 6You became imitators of us and of the Lord, having received the word in much affliction, with joy of the Holy Spirit, 7so that you became an example to all who believe in Macedonia and in Achaia. 8For from you the word of the Lord has been declared, not only in Macedonia and Achaia, but also in every place your faith toward God has gone out, so that we need not to say anything. 9For they themselves report concerning us what kind of a reception we had from you, and how you turned to God from idols to serve a living and true God, 10and to wait for his Son from heaven, whom he raised from the dead: Jesus, who delivers us from the wrath to come.
When Jesus spoke to His disciples in John 14:2, 3, His words provided imagery of a characteristic wedding and marriage in a Middle Eastern community, in which a bridegroom would begin building a room for him and his bride (see photo at John 14:2), and upon completion, there would be a wedding and they would return back to their Father's house (see The Father's House and Marriage Practices in the Middle East (John 14:2, 3)).
Part of this glorious marital event would be the marriage supper. This passage in the Revelation deals with Jesus and His bride the church, who was taken to be with Him before the wrath that was coming upon the earth (1 Thess 1:10), but would return to earth to participate in this joyous supper, after their marriage.
The righteous deeds spoken of in verse 19:8 parallel the time of Jesus, in which a betrothed bride would make herself ready by taking a bath or other means, and would be ready for a wedding gown (Eph 5:25, 26). After the marriage, there would be a great supper, and then return with her to a place prepared for the couple. This imagery follows closely with the events in the relationship of Christ and the church.
