Why did Paul not only say as you say, ‘he died .... and rose from the dead three days later’? But he said TWICE: “He died (’for your sins’) ACCORDING TO THE SCRIPTURES”; and He rose from the dead (’for your sins’) “the third day ACCORDING TO THE SCRIPTURES”? It’s because it was not a mere three consecutive three days long that He would be dead before He would rise again; but because it was THOSE THREE DAYS “according to the Scriptures” the PASSOVER-Scriptures HAVING BEEN FULFILLED by the Antitype of the passover sacrifice. Christ is Truth; the Scriptures’ Truth. “No sign shall be given you except the sign of THE PROPHET, Jonah” — “even though one rose from the dead you won’t believe believed you not MOSES” - the Scriptures!
Have you ever seen an atheist or a denier of Jesus Christ who believes the Scriptures?
