What does the phrase "house has many mansions" refer to in the context of John's teachings?

The phrase "house has many mansions" comes from the Gospel of John, specifically John 14:2, where Jesus reassures His followers about the afterlife and the existence of different dwelling places in heaven. The correct interpretation centers on the idea that there are many rooms or places for believers in the spiritual realm, emphasizing the accessibility of heaven for all who have faith. This teaching conveys inclusivity and hope, assuring followers that there is a place for everyone in heaven, reflecting the boundless nature of divine grace and the personal relationship between believers and God.

The other options do not capture this spiritual meaning. The notion of earthly homes does not align with the heavenly context intended; the diversity of life on Earth is unrelated to the concept of eternal life and afterlife; and the richness of material possessions deviates entirely from the essence of spiritual fulfillment and heavenly promise that the phrase represents.
