The present-day “good News” concerning God's kingdom is that it has been established in heaven in this very generation; yes, that Jesus Christ has been enthroned there and is ruling in the midst of his enemies. This means that Satan the Devil has been cast from heaven to the vicinity of the earth, and that he will soon be abyssed and his entire wicked system of things destroyed. What good news.
In the book Man's Salvation Out of World Distress At Hand 1975 Watchtower Bible and Tract Society on page 47 it says,
The glorification of Jesus Christ in heaven after his extraordinary sufferings as a man on earth was good news, Gospel, Evangel "Nevertheless," writes the apostle Paul with special reference to his own people, "they did not all obey the good news. For Isaiah says: 'Jehovah, who put faith in the thing heard [from] us? So faith follows the thing heard. In turn the thing heard is through the word about Christ." -Romans 10:16,17.
Page 48.
A similar thing can be said today. "They did not all obey the good news." This, even after the christian witnesses of Jehovah have spent more than sixty years in proclaiming the the "times of the Gentiles" ended in the autumn of 1914 C.E. amid the first world war and that then Jehovah's "servant " recieved a new elevation by being exalted to the throne of the Messianic kingdom...
In the face of the relatively small proportion of the world's population that has put faith in the "thing Heard [from] us" or proclaimes by us, it can truthfully be said: "They did not all obey the good news."
DocHouse I think from this it is as it says the 'present day' good news
