Most Christians around the world celebrate the bodily Resurrection of Jesus from the dead on a day that is commonly called Easter. (And no, it is not a “pagan holiday”, nor is it wrong for us to celebrate. Read the material at the links here so you can savvy that, Sam.) Obviously, before he could rise again, he had to die. That day is usually called Good Friday, and many of us observe that day as well.
It seems strange that the day Jesus suffered the most horrible death known is called “good.” It was good for us, as this B.C. comic succinctly puts it. Got Questions explains:
Why is Good Friday referred to as “good”? What the Jewish authorities and Romans did to Jesus was definitely not good (see Matthew chapters 26-27). However, the results of Christ’s death are very good! Romans 5:8, “But God demonstrates his own love for us in this: While we were still sinners, Christ died for us.” First Peter 3:18 tells us, “For Christ died for sins once for all, the righteous for the unrighteous, to bring you to God. He was put to death in the body but made alive by the Spirit.”https://www.gotquestions.org/Good-Friday.html
Although mockers try to say that if the Crucifixion was on Friday and the Resurrection was on Sunday, that’s not three days. Cults also do this for some reason. I remember seeing a television show from one that made this claim. There are honest people who also have puzzled about how three days can be reconciled with Friday afternoon through Sunday morning.
It takes a little bit of homework. Hebrews had a different way of reckoning time. We use the Roman system where a day is split into two halves, but you may have noticed in your Bible that certain things happened at a certain hour, such as when Peter and John went up to the temple at the ninth hour (Acts 3:1), which was about three in the afternoon. Some Bibles render that as “three in the afternoon.”
I say about because they didn’t exactly have digital watches, or even grandfather clocks using weights and pendulums. So, an hour wasn’t. Not really, because hours were based on the amount of sunlight in the day. There were twelve hours in a Jewish day, but as for night, it seems that nobody cared very much; there were watches in the night.
With these things in mind, it should come as no surprise to learn that the Jews counted days differently as well. Modern tend to impose their own cultures, experiences, and opinions on texts of ancient cultures. Someone today, 15 April, could say, “I’ll see you in three days”, and the other person says, “Okay, this is Friday at noon. So I’ll see you…let’s see…Saturday, Sunday, Monday. We’ll meet here at noon on Monday. Bring burgers.”
By letting the ancient culture “say” what it means and not forcing our own views on it, we see there is neither problem nor contradiction.
