The answer is: Jerusalem

Isaiah 2:2-3 - Prophecies in the Old Testament, such as in Isaiah, indicate that Jerusalem will be the center of worship for all nations. This foretells a future where God's presence will draw everyone to His holy city, aligning with Revelation 21:24, which also speaks of nations walking in God's light.

Isn’t it fascinating how grandeur and simplicity often collide in the pages of Scripture? In Isaiah 2:2-3, we find a powerful vision where all nations flow to Jerusalem, not just a city of bricks and walls, but a symbol of unity, peace, and connection with the divine. Imagine countless people gathering, each bringing their diverse traditions and cultures to worship together—it's the ultimate international potluck of faith!

Mark your calendar! Keeping this vision alive, Revelation 21:24 echoes the sentiment with nations basking in the radiance of God’s kingdom. But wait, there’s more! Did you know the name “Jerusalem” itself has deep ties to "peace"? The origin, “shalom”, extends beyond the absence of conflict to embody harmony and completeness. When people ascend to Jerusalem spiritually, it symbolizes a mutual embrace—a heavenly homecoming where differences dissolve, and divine love prevails.

And speaking of reaching new heights, consider that Jerusalem sits on a hill. Its elevated location isn’t just geographical but metaphorical, teaching us that the path to God often involves rising above our everyday troubles and seeking something greater. How interesting that these ancient prophecies say back then what we still aspire to now—a world united under a heartfelt quest for the Sacred. That means whenever wherever people gather to seek and worship, they participate in this magnificent and ongoing mission that spans generations!
