Lol, I'm a little busy.
Bad news, Adam, sin and death
Good news, Jesus, forgiveness of sin and life, everlasting. That is the Gospel. He Himself is the good news. What He accomplished by His death is the good news.
Jesus taught under the law and was bringing the lost people of Israel back to it, to show how utterly impossible it was to gain rightousness through it, and they, if they accept Him as the Messiah, will then turn to His Grace and Mercy for the renewal of life because of His sacrifice.
It's really not that complicated.
