When we hear beautiful music, we want to hear it again and tell others about it. We let it run through our minds again and again. We hum it. This is praise, appreciation. Praise is any form of recognition that someone or something is beautiful or excellent in its kind.
Praise is spontaneous and natural and good.
People who are slow to praise are curmudgeonly and unpleasant to be with. They must find it hard to get along with themselves. Praise is a Christian virtue and necessary for a Christian. Praise is the mark of a humble, thoughtful soul. It is the cure for cynicism and gloom.
