How old was Jesus when He began His public ministry?

• A. About 25 years old
• B. About 30 years old
• C. About 33 years old
• D. About 40 years old

Answer: (B)

The moment Jesus began his public ministry is described as happening when he was about thirty years old. Luke 3:23 records that Jesus “was about thirty years old when he began his ministry,” making this the clearest biblical marker for the start of his public work. The baptism by John the Baptist, which inaugurates that ministry, helps place the timing in the flow of the gospel narrative. Because the text uses the phrase “about thirty,” it signals an approximate age rather than a precise number, but it is the direct reference the question relies on. Other ages aren’t stated as the starting point in the Bible, and while some traditions link the age of thirty-three with the crucifixion, that pertains to a later event in the timeline. So the most accurate answer, given the biblical record, is that Jesus began his public ministry at about thirty.
