Is Our Labor In Vain? 1 Thessalonians 3-4.

For, in fact, we told you before when we were with you that we would suffer tribulation, just as it happened, and you know. For this reason, when I could no longer endure it, I sent to know your faith, lest by some means the tempter had tempted you, and our labor might be in vain. But now that Timothy has come to us from you.For now we live, if you stand fast in the Lord. And may the Lord make you increase and abound in love to one another and to all, just as we do to you, so that He may establish your hearts blameless in holiness before our God and Father at the coming of our Lord Jesus Christ with all His saints. For this is the will of God, your sanctification: that you should abstain from sexual immorality; that each of you should know how to possess his own vessel in sanctification and honor, not in passion of lust, like the Gentiles who do not know God; that no one should take advantage of and defraud his brother in this matter, because the Lord is the avenger of all such, as we also forewarned you and testified. For God did not call us to uncleanness, but in holiness. Therefore he who rejects this does not reject man, but God, who has also given us His Holy Spirit. that you also aspire to lead a quiet life, to mind your own business, and to work with your own hands, as we commanded you, that you may walk properly toward those who are outside, and that you may lack nothing. For if we believe that Jesus died and rose again, even so God will bring with Him those who sleep in Jesus. For the Lord Himself will descend from heaven with a shout, with the voice of an archangel, and with the trumpet of God. And the dead in Christ will rise first. Then we who are alive and remain shall be caught up together with them in the clouds to meet the Lord in the air. And thus we shall always be with the Lord. Therefore comfort one another with these words.
