There are many different kinds of trees in the garden.  
This one is the “Tree of Life” which bears much fruit. The fruits represent all types of people. The purpose of Life is to produce as much fruit as we possibly can. This is our calling!
 
John 15:5 
“I am the vine; you are the branches. If a man remains in me and I in him, he will bear much fruit; apart from me you can do nothing.”
