Jesus’ instructions are clear. We must teach people the things that he commanded. However, we should not overlook an important detail. Jesus did not say: ‘Teach them all the things I have commanded you.’ Instead, he said: Teach them “to observe all the things I have commanded you.” To apply that specific instruction when teaching a Bible student, we need to be not only teachers but also guides. (Acts 8:31) To “observe” a command means to obey it. When we study the Bible with others, we teach them what God requires of us. But we must do more. We must teach our Bible students to apply in their daily life what they learn. (John 14:15; 1 John 2:3) By example, we can show our students how they can apply basic Scriptural principles at school, at work, or during recreation. In the presence of our students, we can pray to Jehovah that the holy spirit guide them.​—John 16:13. w20.11 2-3 ¶3-5

Jesus’ disciples faced challenges. For example, copies of the Scriptures were few. There were no study aids such as we have today. And the disciples had to preach to people who spoke many different languages. In spite of all those challenges, those zealous disciples did the seemingly impossible​—within just a few decades, they had preached the good news “in all creation under heaven.” (Col. 1:6, 23) In modern times, Jehovah continues to direct and empower his people. The direction, of course, comes largely through God’s spirit-inspired Word. There we find a record of Jesus’ ministry and his command that his followers continue the work he started. (Matt. 28:19, 20) Jehovah is impartial; he foretold that the good news would be declared “to every nation and tribe and tongue and people.” (Rev. 14:6, 7) He wants the Kingdom message to be available to all. w20.10 21 ¶6-8

King David was a man who loved “the law of Jehovah.” (Ps. 1:1-3) David knew that Jehovah saves those who are humble but opposes the haughty. So David allowed God’s law to adjust his thinking. He wrote: “I will praise Jehovah, who has given me advice. Even during the night, my innermost thoughts correct me.” (Ps. 16:7) If we are humble, we will allow God’s Word to correct our wrong thinking before we act on those thoughts. God’s Word will be like a voice that tells us: “This is the way. Walk in it.” It will warn us when we are straying from the path​—to the left or to the right. (Isa. 30:21) By listening to Jehovah, we will benefit ourselves in a number of ways. (Isa. 48:17) For instance, we will avoid the embarrassment of having to be corrected by someone else. And we will draw closer to Jehovah because we recognize that he is treating us like a beloved child.​—Heb. 12:7. w20.11 20 ¶6-7
