The answer is: Those that do God's commandments

Rev 22 vs 14

In Revelation 22, the tree of life stands as a profound symbol of eternal joy and restored connection with God—a theme so beautifully woven throughout Scripture. Those who may partake in its fruit are described as those who “do God’s commandments,” suggesting a life intertwined with obedience and moral integrity. This concept echoes back to the Garden of Eden, where the original tree of life was available, establishing a continuous thread of divine provision that bridges humanity's history with God.

Interestingly, the notion of accessing the tree of life wasn’t always a promise for the many. In Genesis 3, after humanity’s disobedience, Eden was guarded to keep us from eternal separation. Yet in the final chapter of the Bible, the restoration is made clear, with the invitation opened wide again to humanity willing to embrace the way of divine wisdom and acting upon it.

Trivia lovers might enjoy noting that the "true" tree of life is referenced in Proverbs as embodying wisdom itself (Proverbs 3:18). Additionally, in a fascinating twist for those pondering correlations, the Gospel of John presents Jesus as the manna from heaven—a striking parallel, redirecting the access to eternal nourishment not through the physical, but through the spiritual.

Thus, this passage in Revelation symbolizes hope—a powerful opportunity for salvation and reconciliation. It beckons all of us to embrace a lifestyle that aligns with higher virtues, ensuring that we remain on the path that leads us back to community with the Divine.
