“About the glory of your kingship they will talk, and about your mightiness they will speak,

(Psalm 145:11, 12) People talk about things that interest them. So a man speaks of his family, his home, his crops. “A good man brings forth good out of the good treasure of his heart,” said Jesus. (Luke 6:45) If God’s rulership is dear to our heart, we will pray for his Kingdom to come, and we will tell others about the justice, peace, and righteousness that will prevail under its rule. We will praise Jehovah as the “King of eternity,” and we will speak about the expression of his sovereignty through the Messianic Kingdom in the hands of his dear Son, Jesus Christ. (Revelation 15:3; Isaiah 9:6, 7) What a privilege it is to speak about the heavenly glory of Jehovah’s kingship, which will soon be reflected in the beauty of an earthly paradise filled with perfectly happy creatures!​—Luke 23:43.

 4. When do we have occasion to speak about Jehovah’s “mightiness,” and how are we sustained in such activity?

⁴ Appreciation will also move us to speak about Jehovah’s “mightiness.” Though “he is exalted in power,” he never misuses it. (Job 37:23) He used his power to create the earth and mankind and will exercise it to destroy the wicked. We have occasion to speak about God’s mightiness when we declare the good news. And are we not grateful that this ultimate Source of strength empowers us to do this work? (Isaiah 40:29-31) Yes, as Jehovah’s Witnesses, we are sustained in sacred service by God’s strength and spirit. It is only in this way that the Kingdom message is being proclaimed with marvelous success worldwide.​—Psalm 28:7, 8; Zechariah 4:6.

 5. Since multitudes do not know about Jehovah’s “mighty acts,” what should we do?

⁵ There is a need for us to make known to the sons of men the “mighty acts” of Jehovah, even as the Israelites told their children about the way God delivered them from Egyptian bondage. (Exodus 13:14-16) Men build monuments to humans whose deeds they consider notable, but how many know about the mighty acts of God? As one scholar put it: “They inscribe the deeds of their heroes upon brass, but the glorious acts of Jehovah are written upon the sand, and the tide of time washes them from present memory.” Those acts are not really washed away, though they are unknown to multitudes. So in our house-to-house work, when conducting home Bible studies, and on other occasions, let us zealously speak of God’s mighty acts.

 6. (a) On what occasion years ago was the zealous spirit with which we carry out our ministry well expressed? (b) In essence, what was said in 1922 about advertising the Kingdom?

⁶ We should also zealously make known the glory of God’s kingship. Zeal for such Kingdom service surely was evident when, in 1922, J. F. Rutherford, then president of the Watch Tower Society, addressed conventioners at Cedar Point, Ohio, and said: “Since 1914 the King of glory has taken his power . . . The kingdom of heaven is at hand; the King reigns; Satan’s empire is falling; millions now living will never die. Do you believe it? . . . Then back to the field, O ye sons of the most high God! Gird on your armor! Be sober, be vigilant, be active, be brave. Be faithful and true witnesses for the Lord. Go forward in the fight until every vestige of Babylon lies desolate. Herald the message far and wide. The world must know that Jehovah is God and that Jesus Christ is King of kings and Lord of lords. This is the day of all days. Behold, the King reigns! You are his publicity agents. Therefore advertise, advertise, advertise, the King and his kingdom.”

 7. How should we feel about our activity as Kingdom proclaimers?

⁷ What a joy to ‘think upon God’s name,’ to tell others about his rulership, and to advertise the Messianic Kingdom of his dear Son! (Malachi 3:16) As Kingdom proclaimers and advocates, we cherish our privilege of declaring the good news and turning the hearts of others toward God, Christ, and the Kingdom. Within us, there should be a burning desire to tell others about the glorious splendor of Jehovah’s kingship.​—Compare Jeremiah 20:9.

 8. (a) In what is Jehovah’s rulership represented today? (b) Why can it be said that God has dominion “throughout all successive generations”?

⁸ We should be moved to announce God’s Kingdom with great zeal, for David next said: “Your kingship is a kingship for all times indefinite, and your dominion is throughout all successive generations.” (Psalm 145:13)
