The answer is: 1

(Matthew 25:15) + (Matthew 25:2) - (Rev 21:21) = (8) + (5) - (12) = 1

Isn’t it fascinating how the scriptures blend in such creative ways? Let's break it down a bit more. In the Parable of the Talents, we see a master entrusting some serious assets to his servants, which undoubtedly sparked discussions about responsibility and stewardship. The total amount given wasn’t just about financial savvy; it was also a lesson on how we utilize the gifts and opportunities presented to us.

Then we swing over to the Parable of the Wise and Foolish Virgins, where oil represents preparation and spirituality—a healthy reminder that readiness is key in our spiritual journey. Five wise virgins were blessed for their foresight, emphasizing not only the importance of keeping 'the light' burning but also reflecting on collective readiness over individual achievement.

Finally, those magnificent twelve gates of the New Jerusalem set the stage for a vision of divine possibilities—anyone familiar with historical interpretations knows this symbolizes a beacon of promise and inclusivity. The portrayal of gates could invoke thoughts about community and eternal embrace.

When churning through these contrasting yet intertwining narratives, what emerges can be a concise yet profound answer we glean—learning how to balance preparedness, stewardship, and community while finding our grand entrance into wisdom. So next time you hear about talents, lamps, or gates, let them remind you of the journey—a journey heavily punctuated with hope and engagement.
