The key to reopen the Garden of Eden is compassion in terms of veganism. “I give you every seed-bearing plant on the face of the whole earth and every tree that has fruit with seed in it. They will be yours for food... God saw all that he had made, and it was very good" (Genesis 1:29-31 NIV). God thereby prescribed a vegan diet to the first humans.
But when Adam and Eve ate the forbidden fruit -- animal flesh -- death and violence entered the world, and Adam and Eve got knocked out of Eden (Chen 2021; Ervin 2010). For God is love (1 John 4:7); God loves the world (John 3:16), including ALL His creation (Psalm 145:9), so much so that He made a Covenant with every animal (Genesis 9:10); and Christ is compassion (Matthew 12:6-7). Thus, the only way to go back to Eden here and now is going vegan, which is an ethical view against cruelty to any sentient creatures of God.
