Tree of life - sustenance and healing for the physical body ... the tree of life, which bare twelve manner of fruits, and yielded her fruit every month: and the leaves of the tree were for the healing of the nations. (Revelation 22:2) Bread of life - sustenance and life giving for the soul I am that bread of life..., if any man eat of this bread, he shall live for ever (John 6:48, 51 ) Water of life (Rev 22:1) - sustenance for the spirit and bearing witness with our spirit that we're sons of God (Rom 8:16) If any man thirst, let him come unto me, and drink. He that believeth on me,... out of his belly shall flow rivers of living water. But this spake he of the Spirit... (John 7:37-39)
