The answer is: 1

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

Let’s unpack some interesting layers of the rich symbolism in this math problem. Each element reflects deeper spiritual teachings and has something practical to offer us.

First, we consider the talents in Matthew 25:15, where a wealthy master entrusts varying amounts to his servants. Talents can represent spiritual gifts, skills, or even responsibilities. In Biblical tradition, they remind us that each gift, big or small, is meant for stewardship. The story isn't just about financial gain but about growing what we have for the common good!

Now, on to the wise virgins in Matthew 25:2, who prepared by bringing enough oil for their lamps. Oil often symbolizes the Holy Spirit or divine providence in both the Old and New Testaments. The requirement of foresight teaches the importance of being spiritually prepared and diligent in our pursuits.

Lastly, we find ourselves at the gates of the New Jerusalem in Revelation 21:21, a city of splendor with twelve gates symbolically made from pearls. Each gate’s number signifies a powerful connection to conflict resolves and divine fulfillment, beautifully bringing together past covenant traditions, Old and New same, echoing a return to paradise or the garden.

So, the answer "1" encapsulates all this interconnectivity—highlighting that spirituality isn’t simply additive or subtracted but evolves through our stewardship and preparations toward a higher, unified goal. Stay lit and thrive in faith!
