The Gospel is not for those who are living the "Good Life." For if one has the good life, in essence, they wouldn't need heaven nor Christ Himself. For they have The Good Life.
The Gospel, on the other hand though is for those who don't have the Good Life. The Gospel is for broken down, beat up, desperate sinners. The Gospel is for those who recognize that they are cheaters, manipulators, thieves, adulterers, murderers... and the list goes on. The Gospel is for those who recognize that they are all of these things and more - and have repented of them.
Come, ye sinners, poor and needy,
Weak and wounded, sick and sore;
Jesus ready stands to save you,
Full of pity, love and power.
