Positive thoughts are love.

Even the mere thought of something positive is an act of love. The joy that someone may radiate through a simple smile, when recognized, is an act of love. If it brings joy to you or makes you think of joyful events in your past, then that is also grounds for loving thoughts toward another. Such relationships are vital in your life. They help to provide meaning to all human life, and they provide a kind of basis for your interactions with others.

Such attitudes are God's response through your spiritual being.
