The Good News Of The Kingdom
Where God reigns there is perfect justice, love etc.. God reigns at the beginning and end of the Bible, in the Grden of Eden and in heaven. In between, of course, we see the the brokenness of the world caused by sin, that is, by the rejection of the kingship of God.
Every healing, deliverance, answered prayer, miracle, conversion is a sign of the reign of God and the defeat of Satan. God's reign is always good news.
The gospel is the news that sin has been paid for, forgiveness and a restored relationship with God are possible. It also reveals the hope/certainty that the King will return and destroy all evil, ushing in the restored Kingdom.
The gospel is about the kingship of God and it is all good news (except for those who reject it).
