And he said unto them, These are the words which I spake unto you, while I was yet with you, that all things must be fulfilled, which were written in the law of Moses, and in the prophets, and in the psalms, concerning me. Then opened he their understanding, that they might understand the scriptures, (Luke 24:44-45)

What "Scriptures" were those disciples to understand? It could not have been the New Testament, because it was not written yet. It was the Old Testament "Scriptures". The Old Testament points us to Christ.
