Boredom

Boredom is a sin, so say the church fathers. This is because when we allow ourselves to become bored, we are saying that we have nothing of value upon which to expend our time and energy. But this is nonsense. The is always something productive to do. There are always prayers to be prayed. There are always sins to confess. There are always neighbors to love. There is always something to learn.
A bored attitude comes from a heart wallowing in and controlled by the passions. It is a heart that needs to be entertained and titillated. Instead, our hearts should be filled to overflowing with love for God and love for our neighbor. When we think of others, rather than ourselves, we will never be bored. When we are striving after holiness, we will always recognize some way of improving our life or the life of someone else.
We must learn to look being our own comfort and entertainment.
