Love Lesson From A Bird

Sadhu Sundar Singh narrated this:
In a Tibetan village I noticed a crowd of people standing under a burning tree and looking up into the branches. I came near and discovered in the branches a bird which was anxiously flying round a nest full of young ones. The mother bird wanted to save her little ones, but she could not. When the fire reached the nest the people waited breathlessly to see what she would do. No one could climb the tree, no one could help her. Now she could easily have saved her own life by flight, but instead of fleeing she sat down on the nest, covering the little ones carefully with her wings. The fire seized her and burnt her to ashes. She showed her love to her little ones by giving her life for them. If then, this little insignificant creature had such love, how much more must our Heavenly Father love His children, the Creator love His creatures!
As Love Creatures, why should'nt we receive this love and reciprocate this kind of love to men?
