“Christ died for our sins according to the scriptures; and that he was buried, and that he rose again the third day according to the scriptures.” 1 Corinthians 15:3b-4.
The fact that Jesus rose bodily from the grave is not so hard to believe. He who made the world and everything in it could defeat death and come out of the grave. And he did it for our sins. Not his, but ours. Yours. Mine. He died, was buried, and rose again, and lives forever. Because he lives, we can have eternal life!
