A kind word is like a spring day.
 - Russian Proverb

Be kind and merciful. Let no one ever come to you without leaving better and happier.
Be the living expression of God's kindness -  kindness in your face, kindness in your eyes, 
kindness in your smile, kindness in your warm greeting.
In the slums, we are the light of God's kindness to the poor. To children, to the poor, all who suffer and are lonely, always give a happy smile. Give them not only your care but also your heart. 
Because of God's goodness and love every moment of our life can be the beginning of great things. 
Be open, ready to receive and you will find Him everywhere. Every work of love brings a person face to face with Almighty God! 
- Mother Teresa, In the silence of the Heart

And it is here that the Saints serve us yet again. Kindness recovers all its Apostolic quality in them. 
In the Saint it is never sentimental; never divorced from reality; never undisciplined; never evasive.
On the other hand, it is ever-present; never excluded by their concern for God's Holiness; never driven away by any pride in their own virtue. The cheapening of the word in the world and the neglect of this grace in the sanctuary are both correct in the Saint. He reveals kindness as a " Fruit of the Spirit '. He shows is grounded in the very Nature of God. It flows directly from His Faith. 
It is Super Natural Love disclosing itself in costly affection towards his fellow humans... That is why it has a robustness and pertinacity unknown to the sentimental kindness of the World! ...
- W.E Sangster, " The  Pure Heart "

" Seek first the Kingdom of God and His Righteousness, and all these things will be given to you! "
