When we have cultivated proper fear of Jehovah, we love him so much that we would never do anything to displease him. We are eager to learn the difference between right and wrong, between truth and falsehood, so that we can gain Jehovah’s approval. (Prov. 2:3-6; Heb. 5:14) If we were to fear humans more than we fear God, we could be led away from the truth. Consider the example of the 12 chieftains who spied out the land that Jehovah had promised to give to the Israelites. For ten of the spies, their fear of the Canaanites was stronger than their love for Jehovah. They told their fellow Israelites: “We are not able to go up against the people, because they are stronger than we are.” (Num. 13:27-31) From a human standpoint, the Canaanites were stronger. That part was true. But to say that the Israelites would not be able to conquer their enemies left Jehovah out of the picture. w24.07 28:5-6

Do we have good reason for confidence regarding all of Jehovah’s judgments, both favorable and unfavorable? Yes! As Abraham understood so well, Jehovah is the perfect, all-wise, merciful “Judge of all the earth.” He has trained his Son and delegated all judging to him. (John 5:22) Both Father and Son can read what lies in each human heart. (Matt. 9:4) In every case, they will do “what is right”! Let us be determined to trust that Jehovah knows best. We recognize that we are not qualified to judge​—but he is! (Isa. 55:8, 9) So we confidently leave all the judging to him and his Son, the King who perfectly reflects his Father’s justice and mercy.​—Isa. 11:3, 4. w24.05 18:18-19

We can learn about the importance of having a sincere heart from Jesus’ first meeting with Nathanael. When Philip brought his friend Nathanael to meet Jesus, something remarkable happened. Although Jesus had never met Nathanael, Jesus said: “See, truly an Israelite in whom there is no deceit.” (John 1:47) Jesus saw in Nathanael an extraordinary sincerity. Like us, Nathanael was imperfect. But there was nothing artificial or insincere about him. Jesus admired that and commended Nathanael for it. Most of the requirements for pleasing Jehovah listed in Psalm 15 are related to how we treat others. Psalm 15:3 states that a guest in Jehovah’s tent “does not slander with his tongue, he does nothing bad to his neighbor, and he does not defame his friends.” Misusing our speech in such ways could cause serious harm to others.​—Jas. 1:26. w24.06 24:7, 9-10
