Hi there is immorality naturally within the human body built in, unfortunately the body needs to be completed with a chemical balance that leads to releasing this within the body, John 4:14 (ERV). This chemical balance repairs and refines our genes so that we are capable of producing a perfect body that removes birth defects and items that are prone to an imperfect body. Since Adam and Eve were not allowed to access the tree of life their body remained incomplete. The tree of life is still the only way to achieve salvation but access to the tree must be allowed.
1 Peter 1:5
Modern English Version (MEV)
5 who are protected by the power of God through faith for a salvation ready to be revealed in the last time.
