When we live by eating the fruit of the tree of the knowledge of "good and evil" we are eating death.
When we live by eating the fruit of the Tree of Life (Jesus Christ), we are eating life.

"He has enabled us to be ministers of his new covenant. This is a covenant not of written laws, but of the Spirit. The old written covenant ends in death; but under the new covenant, the Spirit gives life." 2 Corinthians 3:6 (NLT)

"Do not judge according to appearance, but judge with righteous judgment."
John 7:24 (NLT)
