According to the book of Genesis, God gave life to the first couple, Adam and Eve, and placed them in the Garden of Eden. There, they had access to the Tree of Life, which served as a symbol of the everlasting life He had given them. When Adam and Eve disobeyed God, they were banned from Eden and from eating of the special tree. Where is the Tree of Life now? According to Revelation 22, it is located in heaven.
