The Creator envisioned that perfect humans would cooperate with him to accomplish his purposes. Despite mankind’s current imperfect state, faithful people can still work with Jehovah each day. For example, we become “God’s fellow workers” by preaching the good news of his Kingdom and making disciples. (1 Cor. 3:5-9) Just think what a privilege we have to be counted worthy of cooperating with the almighty Creator of the universe in a work that he considers important! Yet, preaching and making disciples are not the only ways that we work with Jehovah. Other ways we can do so are by assisting our family and fellow worshippers, by being hospitable, by volunteering for theocratic projects, and by expanding our sacred service. (Col. 3:23) However, do not compare what you can do for Jehovah with what others can do. Remember that age, health, circumstances, and abilities vary from one person to another. w18.08 23 ¶1-2

Doing what we know to be right brings rich blessings. Although wisdom is based on knowledge, it particularly has to do with the decisions we make rather than just the facts we understand. Even ants reveal wisdom. Ants demonstrate instinctive wisdom by preparing their food in the summer. (Prov. 30:24, 25) Christ, “the wisdom of God,” always does the things pleasing to the Father. (1 Cor. 1:24; John 8:29) God knows the difference between making the right choice and acting on that choice. And he rewards those who demonstrate humility with endurance and who practice what they know to be true. (Matt. 7:21-23) Therefore, work to preserve the spiritual environment in which genuine humility can flourish. Applying what we know to be true takes time and requires patience, but it is a mark of humility that leads to happiness now and forever. w18.09 7 ¶18

To keep our hearts pure, we must be clean on the inside and nurture chaste affections and desires. We need to keep our thoughts clean so as to be spiritually untainted in our devotion to Jehovah. (2 Cor. 4:2; 1 Tim. 1:5) How, though, do the pure in heart “see God” when, in fact, “no man can see [God] and live”? (Ex. 33:20) The Greek word rendered “see” can carry the sense of “to see with the mind, to perceive, know.” Those who see God with ‘the eyes of the heart’ are those who have really come to know him, appreciating his qualities. (Eph. 1:18) In addition to getting to know God’s qualities, true worshippers can “see God” by observing the way he acts in their behalf. (Job 42:5) They also focus ‘their eyes of the heart’ on the wonderful blessings that God holds out for those who strive to remain pure and to serve him loyally. w18.09 20 ¶13, 15-16

What device has had the worst possible effect on humankind? The lie! That is, saying something that one knows is not true in order to deceive someone else. And who devised the first lie? Jesus Christ identified “the Devil” as “the father of the lie.” (John 8:44) When did he utter the first lie? It happened thousands of years ago in the garden of Eden. The first human couple, Adam and Eve, were enjoying life in the Paradise that their Creator had provided for them. Then, the Devil entered the scene. He knew that God had commanded the couple not to eat from “the tree of the knowledge of good and bad,” lest they die for their disobedience. Even so, through a serpent, Satan told Eve: “You certainly will not die [the first lie ever told]. For God knows that in the very day you eat from it, your eyes will be opened and you will be like God, knowing good and bad.”​—Gen. 2:15-17; 3:1-5. w18.10 6 ¶1-2

When our life takes an unexpected turn, the changes that we have to face may cause us apprehension and emotional stress. (Prov. 12:25) We may even find it hard to accept those changes. In such circumstances, how can we ‘calm and quiet’ our soul? (Ps. 131:1-3) Despite adverse circumstances, we today can experience firsthand the soothing effect of “the peace of God” that guards our mental powers. (Phil. 4:6, 7) Thus, if we turn to Jehovah when we feel overwhelmed by anxiety, God’s peace can strengthen our determination to reach spiritual goals and guard us against any tendency to give up. In addition to calming us down, God’s spirit can draw our attention to key scriptures that will help us to keep our spiritual priorities.​—John 14:26, 27. w18.10 27 ¶2; 28 ¶5, 8

To walk in the truth, we must accept and obey all of Jehovah’s sayings. We must give the truth priority in our lives and live according to Bible principles. Like David, we must be firmly resolved to keep walking in God’s truth. If we are not, we could have second thoughts about what we paid for the truth and perhaps be tempted to begin taking back part of the payment. Rather, we carefully hold on to the complete truth. We recognize that we cannot pick which truths to accept and which to ignore. After all, we must walk in “all the truth.” (John 16:13) To avoid drifting away from the truth, we must make wise use of our time. If we are not careful, we might start to spend excessive amounts of time on recreation, hobbies, browsing the Internet, or watching television. Although these things are not wrong in themselves, the time we spend on them can begin to encroach on time previously spent in personal study and other spiritual activities. w18.11 10 ¶7-8

True Christians also have this reason to be drawn to God’s love: He “loved the world so much that he gave his only-begotten Son, so that everyone exercising faith in him might not be destroyed but have everlasting life.” (John 3:16) What love Jesus also showed in giving his life for us! And what a powerful motivation that love is for us! God’s Word promises that not even “tribulation or distress” can “separate us from the love of the Christ.” (Rom. 8:35, 38, 39) When we grapple with trials that are physically, emotionally, or spiritually draining, the compelling force of Christ’s love can give us the strength to endure. (2 Cor. 5:14) Jesus’ love has the power to sustain us and to motivate us not to give up, even in the face of such trials as disasters, persecution, personal disappointments, or gnawing anxiety. w18.09 14 ¶8-9
