What can we learn from the apostle Paul’s words to the Thessalonians? When we hear something that does not harmonize with what we have learned from the Bible or when we hear a sensational rumor, we need to use discernment. In the former Soviet Union, our enemies once circulated a letter that was allegedly from world headquarters. The letter encouraged some of the brothers to form a separate, independent organization. The letter itself appeared to be genuine. But faithful brothers were not fooled. They realized that the message the letter contained did not line up with what they had been taught. Today, enemies of the truth sometimes use modern technology in an effort to confuse and divide us. Rather than be “quickly shaken from [our] reason,” we can protect ourselves by considering whether what we hear or read is in harmony with the truths we have already learned.​—2 Thess. 2:2; 1 John 4:1. w24.07 28:14-15

The most important decision that any person can make is the decision to dedicate himself to Jehovah and to become part of His family of worshippers. Jehovah desires everyone to do so. Why? He wants them to enjoy a friendship with him and to live forever. (Deut. 30:19, 20; Gal. 6:7, 8) However, Jehovah does not force anyone to serve him. He allows each individual to decide what he will do. What if a baptized Christian breaks God’s law, committing a serious sin? If he does not repent, he must be removed from the congregation. (1 Cor. 5:13) Yet, even then, Jehovah fervently hopes that the wrongdoer will return to Him. In fact, that is an important reason why he provided the ransom​—to make forgiveness possible for repentant sinners. Our loving God warmly appeals to wrongdoers, urging them to repent.​—Zech. 1:3; Rom. 2:4; Jas. 4:8. w24.08 33:1-2

By the time the apostle John wrote his third letter, some individuals were spreading false teachings and causing divisions. However, others continued “walking in the truth.” They obeyed Jehovah and were “walking according to his commandments.” (2 John 4, 6) These faithful Christians brought joy not just to John but also to Jehovah himself. (Prov. 27:11) What is the lesson for us? Faithfulness leads to joy. (1 John 5:3) For example, we have the joy of knowing that we make Jehovah happy. He rejoices to see us reject the temptations of the world and accept the truth. Others in heaven also rejoice. (Luke 15:10) We too can find joy in seeing one another remain faithful. (2 Thess. 1:4) Then when this system passes away, we will have the satisfaction of knowing that we demonstrated our loyalty to Jehovah even in a world dominated by Satan. w24.11 45:17-18
