Happy or Blessed?

When people ask me how I'm doing sometimes I respond with "I'm blessed". But what does that really mean? Does it mean that I'm happy? The word blessed means more than happy because happiness is an emotion often dependent on outward circumstances. Blessed however refers to the ultimate well being and distinctive spiritual joy of those who share in the salvation of the kingdom of God. So which is it? Am I happy or am I blessed? I'm blessed.
