God wants us to have this fruit of life in us as much as He did in Adam's day. In the Garden was both a River of Life and Fruit of Life. Spiritual drink and food. God wanted His life in man since Eden. And Adam would get it by eating the fruit of life.
Same plan stands today.
Life is to be put in us. But it is through Jesus Christ now. We are told to eat righteousness and drink it. And Jesus continually said that His flesh is bread and His blood is wine. Communion shows the putting into ourselves the bread and wine of Jesus flesh and blood.
