What does Genesis 3:24 mean?
Genesis 3 ends with our last glimpse of the Garden of Eden, of the paradise God had built for the first humans. Sinful man could not be allowed to become immortal by eating from the Tree of Life. While this might seem cruel, it is actually an act of mercy. Existing forever in a fallen, earthly state, separated from God, would have been a fate worse than death. Humans die, but we have the opportunity at an eternal, restored relationship afterwards. Preventing access to the Tree of Life is so essential to God that He sets a guard at the entrance to the garden.The Bible describes different varieties of angels. Angels are not former or future humans. They are specially created race of supernatural beings that serve God and carry out His plans in heaven and on earth. God's Word tells us many things about them, but there is clearly much we do not know.
This is the first mention of a cherubim in Scripture. Cherubim angels are mentioned over 90 times in the Old Testament. Ezekiel 1 and 10 describe them as powerful winged creatures. They almost always serve in the capacity of guarding or protecting what belongs to God or even His own presence. Here a cherubim is assigned to guard the way to the Tree of Life.
