Question: How old was Jesus when He was crucified on he cross? When exactly did He arise again? Where is this in the Bible?
Response: Thanks for your e-mail. This question(s) is one of those things which the Bible does not state straight out, but which can be worked out, utilizing a close treatment of the texts, historical sources, and systematic theology. To start with, since Jesus rose three days after His crucifixion (Friday to Sunday, counting inclusively as was the custom in the ancient world), He was the same age in calendar years for both events (given that He did indeed most likely have a December birthday and the crucifixion occurred in April). The biblical information for these conclusions is found mostly in the four gospels. For example, Luke says that Jesus was "about thirty" when He began His public ministry (Lk.3:23). I have tried to show that this would have been just before His thirtieth birthday in late A.D. 29 (see link below). Thus, adding a three and one half year ministry (required on the basis of chronological information throughout John's gospel), yields a date for the crucifixion/resurrection of spring A.D. 33, making our Lord's age at that time 33 (and roughly three months). The other details, scriptures and arguments (along with a chronological chart of this) can be found at the following link: "The Life of Christ" in part 5 of the Satanic Rebellion series.

Hope this helps,
