Some people feel embittered all the time. Everything makes them uneasy. They go to sleep with a physical obsession: that this sleep, the only possible escape, is not going to last very long. They wake up with the unwelcome and disheartening feeling that they now have another day in front of them.
Many have forgotten that the Lord has placed us in the world on our way to eternal happiness. They do not realise that only those who walk on earth with the joy of the children of God will be able to attain it.
