Here is the good news (i.e. the declaration of Christ's victory over sin, death and hell).
1 Cor. 15:1-8 (WEB)
1 Now I declare to you, brothers, the Good News which I preached to you, which also you received, in which you also stand,
2 by which also you are saved, if you hold firmly the word which I preached to you—unless you believed in vain.
3 For I delivered to you first of all that which I also received: that Christ died for our sins according to the Scriptures,
4 that he was buried, that he was raised on the third day according to the Scriptures,
5 and that he appeared to Cephas, then to the twelve.
6 Then he appeared to over five hundred brothers at once, most of whom remain until now, but some have also fallen asleep.
7 Then he appeared to James, then to all the apostles,
8 and last of all, as to the child born at the wrong time, he appeared to me also.
