What is the Gospel? According to 1 Corinthians 15:1-4, the Gospel is embodied in these words: "Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand; By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain. For I delivered unto you first of all that which I also received, how that 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 2:2 says, "For I determined not to know any thing among you, save Jesus Christ, and him crucified."
Ray Ortlund said, "Second, the gospel says, ‘he was buried,’ emphasizing that the sufferings and death of Jesus were utterly real, extreme, and final. The Bible says, ‘So they went and made the tomb secure by sealing the stone and setting a guard.’ After killing Him, His enemies made sure everyone would know Jesus was stone dead. Not only was our Lord’s death as final as death can be, it was also humiliating: ‘And they made his grave with the wicked.’ In His astonishing love, Jesus identified with us sinners and sufferers fully, omitting nothing."
