What is the most important feature of every human being? Is it his/her abilty to work, to create facilities or improvements? Some of us will agree with this statement. Yet, the core of the Human Sprirt is determined only by LOVE.
Can an ant(undoubtly the greatest builder known in the animal kingdom) love or be loved? Of course not.
It is obvious then that fulfilment of our mission in this world is strongly connected with our intimacy with the other persons - among which God is the greatest one.
