In Genesis 3 vs 22-24 Adam & Eve are driven from the Garden to prevent them from eating from the tree of life. In Revelation 2 v 7 our Lord says "to the one who is victorious I will give the right to eat from the tree of life, which is in the paradise of God. Are men mortal both physically (obviously) and spiritually? When John writes in Rev 20 v 14 that the lake of fire is the second death, it sounds as if he is saying that men are mortal and are destroyed. How do you see this ?
