How can we strengthen our determination to go on walking in the truth? One way is to have as full a share as possible in teaching Bible truth to others. In this way you will keep a firm grip on our spiritual sword, which is “God’s word.” (Eph. 6:17) All of us can strive to improve our skills as teachers, “handling the word of the truth aright.” (2 Tim. 2:15) As we use the Bible to help others to buy truth and reject falsehoods, we embed God’s sayings in our own mind and heart. In this way, we strengthen our determination to go on walking in the truth. The truth is a precious gift from Jehovah. By means of this gift, we have our most prized possession, our intimate relationship with our heavenly Father. What he has taught us until now is only the beginning! God has promised us an eternity to add to the truth we have already bought. Therefore, cherish the truth like a fine pearl. Continue to “buy truth and never sell it.”​—Prov. 23:23. w18.11 2:2, 15-17

Noah’s preaching work prior to the Flood evidently included a warning of coming destruction. Note what Jesus stated: “For as they were in those days before the Flood, eating and drinking, men marrying and women being given in marriage, until the day that Noah entered into the ark, and they took no note until the Flood came and swept them all away, so the presence of the Son of man will be.” (Matt. 24:38, 39) Despite the people’s indifference, Noah faithfully proclaimed the warning message that he had been given. Today, we preach the Kingdom message to give people an opportunity to learn about God’s will for mankind. Like Jehovah, we dearly wish that people would respond to the message and “keep living.” (Ezek. 18:23) At the same time, when we preach from house to house and in public areas, we warn as many people as possible that God’s Kingdom will come and bring an end to this ungodly world.​—Ezek. 3:18, 19; Dan. 2:44; Rev. 14:6, 7. w18.05 2:8-9

What should you do if the authorities restrict the Kingdom activity in your land and you are called in for questioning about your brothers? Must you tell them everything you know? What did Jesus do when he was interrogated by the Roman governor? In line with the Scriptural principle that there is “a time to be silent and a time to speak,” Jesus at times said nothing at all! (Eccl. 3:1, 7; Matt. 27:11-14) In such a setting, discretion is the better course, so that we do not put our brothers at risk. (Prov. 10:19; 11:12) What will you do if a close friend or relative has committed a serious sin and you know about the matter? “Tell the truth.” You have a responsibility to tell the elders the whole truth, and you must not distort it. They have a right to know the facts so that they can determine the best way to help the wrongdoer restore his or her relationship with Jehovah.​—Jas. 5:14, 15. w18.10 1:17-18
