But have you ever wondered how precise that number is, or why we assume that was his age, especially when Scripture doesn’t specify?

So now I’m going to try and present the evidence, rather than rely solely on tradition and assumptions, and piece together what the Gospels, early Church Fathers, historical data, and even astronomy can tell us about the potential age of Jesus and the length of his ministry.
