If we could triumph over evil by human effort alone, then we would not need a Savior.
Blame others. That way we never have to face the fact that we need to correct ourselves. This is the mark of fools.
As the hands of the potter shape and mold the clay vessel, so trials and tribulations shape our life. They can make us bitter or better.
It is easier to blame someone else for our misfortune than to take responsibility ourselves.
