To be grateful is to recognize unconditional love. It is very easy to say "I'm grateful" and "I love you." Words can slip right off the tongue when you want to get your message across to someone. However only deeds unselfishly acted upon display the true meaning of unconditional love.
When you have found someone who is there for you at your darkest moments, that is a true friend. When they instinctively know what you need and provide you with what you need without you even asking for anything, that is rare and beautiful.
To be grateful we need to recognize unconditional love and hold it steadfast within the depths of our soul.
