In God's creation, He put man in front of the tree of life...  If we visualize the picture of the garden of Eden, according to God's design, we can see the tree of life as the center of our spiritual universe. God's intention is for us to enjoy the tree of life.

God is life. Our taking the tree of life is like enjoying God as our food, our bread of life. 

 Jesus said," I have come that they may have life and may have it abundantly."(John 10:10)  Whenever we respond to Jesus, such as by offering a prayer of praise to Him, we sense the satisfaction of life.

Life is so powerful, so rich, so crucial, yet so simple and clear, when we breathe Him in.
