What does it mean that Christ is the Tree of Life?

Revelation 2:7 states that to those who overcome, God grants access to eat from the Tree of Life. This symbolically represents Jesus Christ Himself, who is the source of eternal life. Unlike the forbidden fruit in Genesis, which brought death, Christ offers life through His sacrifice and resurrection. Believers are clothed in His righteousness, which grants them the right to eternal life, as affirmed in John 3:16. Therefore, Christians see Christ not only as the way to eternal life but also as the sustainer of that life.
