And Jesus went throughout all the cities and villages, teaching in their synagogues and proclaiming the gospel of the kingdom and healing every disease and every affliction. (ESV Matthew 9:35) 

The scroll of the prophet Isaiah was handed to him. Unrolling it, he found the place where it is written: 18 "The Spirit of the Lord is on me, because he has anointed me to preach good news to the poor." (NIV Luke 4:17)  

Humanity’s ultimate problem is death/suffering/sickness and its root of wickedness and rebellion (i.e. bad news). The biblical gospel (i.e. good news) boldly declares to the sick and dying the overturning and conquering of death in the resurrection of the body. Moreover, it declares to the poor and oppressed the uprooting and destruction of wickedness in the judgment of the Day of the Lord. - John P. Harrigan
