Note two important points in the above psalm: (1) Righteous people face problems. (2) Jehovah delivers us from our trials. How does Jehovah deliver us? One way is by helping us to have a realistic view of life in this system of things. While Jehovah does promise that we will have joy in serving him, he does not guarantee a worry-free life now. (Isa. 66:14) He urges us to focus on our future​—the time when we will have the life that he wants us to enjoy forever. (2 Cor. 4:16-18) In the meantime, he helps us to keep going each day. (Lam. 3:22-24) What can we learn from the examples of faithful worshippers of Jehovah, both in Bible times and in our day? We may face unexpected problems. But when we lean on Jehovah, he will never fail to sustain us.​—Ps. 55:22. w23.04 17:3-4

We can learn from the examples of Joseph and Mary, who were ready to obey the superior authorities even when it was inconvenient. (Luke 2:1-6) When Mary was about nine months pregnant, she and Joseph faced a test of obedience. Augustus, who ruled the Roman Empire, called for a census. Joseph and Mary had to travel to Bethlehem, a journey of up to 150 kilometers (93 mi) through hilly country. That trip would be uncomfortable, especially for Mary. The couple may have worried about her safety and that of their unborn baby. What if she were to go into labor while traveling? She was carrying the future Messiah in her womb. Would that excuse them from obeying the government? Joseph and Mary did not allow any of those concerns to influence whether they would obey the law. Jehovah blessed their obedience. Mary arrived safely in Bethlehem, gave birth to a healthy baby, and even helped to fulfill Bible prophecy!​—Mic. 5:2. w23.10 42:9, 11-12

What if the very thought of commenting at meetings makes you nervous? You may find it helpful to prepare well. (Prov. 21:5) The more familiar you are with the material, the more at ease you will feel about volunteering to comment. Also, make your comments brief. (Prov. 15:23; 17:27) A short answer gives you less to worry about. By making a brief comment in your own words, you will show that you have prepared well and that you have a clear understanding of the material. What if you try some of these suggestions but still feel too anxious to comment more than once or twice? Be assured that Jehovah will appreciate your sincere efforts to do what you can. (Luke 21:1-4) Giving your best does not mean putting an unbearable strain on yourself. (Phil. 4:5) Determine what you can do, set a goal to do it, and pray for a calm heart. Initially, that goal may be to make one brief comment. w23.04 18:6-8
