The Good News about the Kingdom are:
Revelation 14:6 And I saw another angel flying in midheaven, and he had everlasting good news to declare to those who dwell on the earth, to every nation and tribe and tongue and people. 7 He was saying in a loud voice: “Fear God and give him glory, because the hour of judgment by him has arrived, so worship the One who made the heaven and the earth and the sea and the springs of water.”
2 Corinthians 2:14 But thanks be to God, who always leads us in a triumphal procession in company with the Christ and through us spreads the fragrance of the knowledge of him in every place! 15 For to God we are a sweet fragrance of Christ among those who are being saved and among those who are perishing; 16 to the latter ones an odor of death leading to death, to the former ones a fragrance of life leading to life…
Matthew 24:14 And this good news of the Kingdom will be preached in all the inhabited earth for a witness to all the nations, and then the end will come:
30 Then the sign of the Son of man will appear in heaven, and all the tribes of the earth will beat themselves in grief, and they will see the Son of man coming on the clouds of heaven with power and great glory.
Good news to those who want righteousness, bad news for those who like unrighteousness.
