The foremost reason why we share in the preaching work is to glorify Jehovah and sanctify his name before mankind. (John 15:1, 8) Yet, we cannot make God’s name more sacred. It is already sacred, or holy, in the absolute sense. But note what the prophet Isaiah stated: “Jehovah of armies​—he is the One you should regard as holy.” (Isa. 8:13) We sanctify God’s name, among other ways, by regarding it as separate from all other names and by helping others to regard it as holy. For instance, by proclaiming the truth about Jehovah’s wonderful qualities and his unchangeable purpose for mankind, we defend God’s name against Satan’s lies and slander. (Gen. 3:1-5) Also, when we strive to help people in our territory to see that Jehovah is worthy “to receive the glory and the honor and the power,” we sanctify God’s name.​—Rev. 4:11. w18.05 18 ¶3-4
