The answer is: 10

(Matthew 4:2) / (Matthew ... John) = (40) / (4) = 10

The story of Jesus fasting for 40 days and nights in the wilderness is one of the most talked-about events in the New Testament. It emphasizes the choice of solitude for personal growth and is a testament to His preparation for ministry. When you divide those 40 days by the four Gospel writers—Matthew, Mark, Luke, and John that gives us 10. This little nugget is more than just a numerical fact; it's a peek into how many angles we can approach Jesus' significance through separate yet complementary accounts.

Every Gospel writer has their unique style and perspective, enriching our understanding of Jesus. Interestingly, Mark is the shortest and least detailed. He quickly glances over the temptation story, focusing more on the action and urgency of Jesus’ mission. On the other hand, Matthew takes his time, offering a detailed account filled with theological themes such as fulfillment of Jewish prophecy and the nature of Jesus as the new Israel enduring His trials.

Let's not forget that 40 days isn’t just random! It’s a significant number throughout the scriptures. For instance, Moses fasted for 40 days before receiving the Ten Commandments. Even the Israelites wandered for 40 years in the desert. This pattern keeps cropping up, suggesting a period of testing, trial, and, ultimately, transformation. Such echoes invite us to reflect on our journeys with faith and how we might be called to look deeper into personal trials, considering them as steps toward spiritual awakening.
