At Thessalonica, Paul had so fully presented the signs of the times that would happen before the Son of man returns in the clouds of heaven that he did not write very much on this subject. However, he pointedly referred to his earlier teachings: “Concerning the times and the seasons, brethren, you have no need that I should write to you. For you yourselves know perfectly that the day of the Lord so comes as a thief in the night. For when they say, ‘Peace and safety!’ then sudden destruction comes upon them.” ULe 96.6
Today the signs of the end are quickly being fulfilled. Paul teaches that it is sinful to be careless about the signs that will precede the second coming of Christ. He calls people who are guilty of this children of darkness: “But you, brethren, are not in darkness, so that this Day should overtake you as a thief. You are all sons of light and sons of the day. We are not of the night nor of darkness.” ULe 96.7
To those living so near the great day of Jesus’ coming, the words of Paul should be all the more important: “Let us who are of the day be sober, putting on the breastplate of faith and love, and as a helmet the hope of salvation. For God did not appoint us to wrath, but to obtain salvation through our Lord Jesus Christ, who died for us, that whether we wake or sleep, we should live together with Him.” ULe 97.1
Watchful Christians try to do all in their power to advance the gospel. They have severe trials, but they do not allow hard experiences to sour their outlook or destroy their peace of mind. They know that if they bear their trials well, the trials will purify them and bring them into closer fellowship with Christ. ULe 97.2
The believers in Thessalonica were annoyed by people who came among them with fanatical ideas. Some were living “in a disorderly manner, not working at all, but are busybodies.” Some, self-willed and rash, refused to follow the instruction of those who held authority in the church. They claimed the right to urge their views on the church publicly. Paul called the attention of the Thessalonians to their obligation to show respect to those who had been chosen to fill positions of authority in the church. ULe 97.3
The apostle pleaded with them to reveal practical godliness in their daily life: “You know what instructions we gave you through the Lord Jesus. For this is the will of God, your sanctification: that you abstain from fornication. ... For God did not call us to impurity but in holiness” (NRSV). ULe 97.4
Paul wanted them to increase in their knowledge of Jesus Christ. He would often meet with little groups of men and women who loved Jesus, and bow with them in prayer, asking God to teach them how to maintain a living connection with Him. And he often pleaded with God to keep them from evil and help them to be earnest, active missionaries. ULe 97.5
One of the strongest evidences of true conversion is love to God and to others. “Concerning brotherly love,” the apostle wrote, “you have no need that I should write to you, for you yourselves are taught by God to love one another. ... Aspire to lead a quiet life, to mind your own business, and to work with your own hands, as we commanded you, so that you may walk properly toward those who are outside, and that you may lack nothing.” ULe 97.6
“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.” ULe 97.7
Paul cautioned the Thessalonians not to despise the gift of prophecy: “Do not quench the Spirit. Do not despise prophecies. Test all things; hold fast what is good.” He urged them to pay careful attention to distinguishing the false from the true, and he closed his letter with the prayer that God would sanctify them fully, that in “spirit, soul, and body” they might “be preserved blameless at the coming of our Lord Jesus Christ.” He added, “He ... will do it.” ULe 97.8
