1 Corinthians 15:3–4 (AV)
3For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures;
4And that he was buried, and that he rose again the third day according to the scriptures:
At the time all the scriptures in existence were the Old Testament scriptures.
Sometimes the Gospel was obvious...
Jeremiah 31:31–34 (AV)
31Behold, the days come, saith the LORD, that I will make a new covenant with the house of Israel, and with the house of Judah:
32Not according to the covenant that I made with their fathers in the day that I took them by the hand to bring them out of the land of Egypt; which my covenant they brake, although I was an husband unto them, saith the LORD:
33But this shall be the covenant that I will make with the house of Israel; After those days, saith the LORD, I will put my law in their inward parts, and write it in their hearts; and will be their God, and they shall be my people.
34And they shall teach no more every man his neighbour, and every man his brother, saying, Know the LORD: for they shall all know me, from the least of them unto the greatest of them, saith the LORD: for I will forgive their iniquity, and I will remember their sin no more.
Sometimes in a less likely place...
Psalm 51:13 (AV)
13Then will I teach transgressors thy ways; and sinners shall be converted unto thee.
But when the Bereans who were commended by Paul searched the scriptures daily to see if what he taught was true or not (Acts 17:11), it was the Old Testament they searched.
I found through searching for Jesus and the Gospel in the Old Testament a richer / fuller understanding of him and the Gospel and have become less prone to fall for traditions typically focused on limited portions of New Testament scripture. Not to disparage the New Testament in any way. The Old Testament provides the background for the New Testament in so many ways as to colorize black and white imagery.
