And so later in the chapel I asked myself: Am I praising Him with my lips and betraying Him with my heart, like the people of Jerusalem? The question made me uncomfortable. (It should probably make you uncomfortable too, if you really think about it.)
Ultimately, the fruit of my prayer with this question was that I must not simply praise the Lord with my mouth, casually or superficially when life is peachy. No, I must praise Him from the very depth of my being, thanking Him at all times for the love and mercy He continually showers upon me. During the Mass I must turn towards Christ as He enters through the gates of my heart, disguised under the appearance of bread, and I must praise Him with my whole self. And later, when I leave, I cannot turn away from Him, for He still resides in my heart. My whole life must proclaim the glory of the Lord.
