What is mercy, and why should we show mercy? This is an important question for us to ask if we wish to truly live out our faith. What does it mean to be merciful, and how are the merciful blessed?
The world may not see it, but the merciful truly are blessed. As Jesus used it here, the word "mercy" is close to the meaning of "happy". Although this word means more than simply being happy, "happy" is one of the words that can be used to attempt to portray the true meaning of this word. A more accurate definition for this word, however, would be "the happiness that comes from being right with God." What Jesus was pointing out to the crowds is that those who are merciful will be happy because they have done right in God's eyes.
This is something truly unique about the Christian life. As Christians, we can actually get a type of happiness from being right with God. No other religion can claim this, and atheism definitely cannot claim to get happiness from being right with God! However, those of us who have been made right with God through Jesus Christ can experience this happiness when we show mercy.
