Love and Gratitude are the two most desirable, fundamental qualities of any human being.
The human being is born to Love. As a child, he is attached closely to his mother and loves her the most. Thereafter, he begins noticing all the other things in the environment and gradually gets attracted by them and falling in love with them. Everything makes him wonder with awe and appreciate it.
While doing so, he would begin to think of the creator of those beauties of nature and begins to realize that he should appreciate the generosity and warmth of that invisible power which is so kind and loving towards humanity for bestowing all that happiness to the mankind. He begins to be thankful and express his gratitude to that Almighty Power.
Even though there is no eternal or continuous happiness in your life, you should notice that, in most cases, you are able to pass through those difficult periods of life with your confidence and faith. This confidence and faith are the tools provided to you by the almighty to guard you always.
So, we need to be grateful to God for being empowering us with these amazing qualities of Love and Gratitude which are essential for our survival on earth.
