Do you find it difficult to grasp the idea that Jehovah has existed “for all eternity”? (Isa. 40:28) That is not unusual. Elihu said of God: “The number of his years is beyond comprehension.” (Job 36:26) But just because we do not understand something does not mean that it is untrue. For example, though we may not understand fully how light works, does this mean that light does not exist? Not at all! Similarly, we humans may never fully comprehend how it is that Jehovah has always existed and will always exist. But this does not mean that God does not live eternally. The Creator is not limited by what we can or cannot understand. (Rom. 11:33-36) And he existed before the material universe​—including light sources such as the sun—​came to be. Yes, he existed before he “stretched out the heavens.”​—Jer. 51:15. w22.12 2-3 ¶3-4

At times, we are invited to offer a prayer on behalf of others. For example, a sister who is conducting a Bible study may ask the sister who has accompanied her to offer a prayer. The visiting sister might not know the student well, so she might prefer to offer the concluding prayer at the study. In that way, she can more easily adapt her prayer to the needs of the student. A brother may be asked to pray at a meeting for field service or at a congregation meeting. Brothers who have that privilege should keep in mind the purpose of the meeting. Prayer is not to be used to counsel the congregation or to make announcements. For most congregation meetings, a total of five minutes is allotted for song and prayer, so the brother who is offering the prayer need not use “many words,” especially at the beginning of a meeting.​—Matt. 6:7. w22.07 24 ¶17-18

Jesus foretold that during the last days, there would be pestilences, or widespread diseases, “in one place after another.” (Luke 21:11) How does knowing that bring us peace? We are not surprised by disease outbreaks. We realize that events are proceeding as Jesus said they would. We thus have reason to follow the advice Jesus gave to those living during the time of the end: “See that you are not alarmed.” A disease outbreak will no doubt disrupt some aspects of your routine, but do not let it interfere with your personal study or meeting attendance. The real-life experiences found in our publications and videos will remind you that your brothers and sisters are keeping their integrity despite similar challenges. w22.12 17 ¶4, 6
