Why is the tree of life significant in Christianity?

The tree of life, first mentioned in Genesis, symbolizes eternal life and perfect communion with God. After Adam's sin, humanity was barred from accessing the tree to prevent eternal separation from God. However, Revelation 22 depicts the tree of life as restored, illustrating God's redemptive plan through Christ. The tree bears fruit every month, signifying the continuous provision of life and spiritual nourishment available to believers. In Christ, we regain access to this eternal life, highlighting God's grace and mercy in drawing sinners back to Himself.
