Mark 15:25 – It was the third hour when they crucified him.
John 19:14,15 – It was the day of Preparation of Passover Week, about the sixth hour. “Here is your king,” Pilate said to the Jews. But they shouted, “Take him away! Take him away! Crucify him!” “Shall I crucify your king?” Pilate asked. “We have no king but Caesar,” the chief priests answered. Finally Pilate handed him over to them to be crucified.
Upon first glance, it seems that there is a blatant contradiction but upon just the slightest bit of research, a person with an ounce of intellectual integrity would quickly realize that the two different authors were using two different systems for marking time. During the time of Christ, in Israel, there were 2 calendars as well as 2 systems for telling time. It all depends on which system was being used by the author. Once could use the Roman calendar and time telling system while another could be using the Jewish calendar. The author John, uses the Roman system for telling time while the author Mark, uses the Jewish system for telling time. They both say the same thing. We have a similar system today. When the clock strikes 1 P.M. I can say, “it’s one o’clock” or I could say “it is thirteen o’clock”. I use two different numbers to say the same thing. Again, just a little bit of thought and research and one can see that there is no contradiction here.
Roman time went from midnight to midnight. The Jewish 24 hour time period began in the evening at 6 pm and the morning of that day began at 6 am. Thus Mark is stating that Jesus was crucified at 9 am and John is stating that the trial was still on at 6 am. (http://www.apocalipsis.org/difficulties/thirdhour.htm)
The point is, Jesus Christ was crucified. He was crucified to pay the price for your sins. He stood in your place and took your punishment. Are you grateful for that? He was not only crucified to pay the price for your sins but He also resurrected so that you can be set free from your slavery to sin (so that you can say “”NO” to sin and temptation). Have you received this amazing offer?
