In today's Gospel reading from John 10, the Jews tried to stone Jesus for blasphemy, for their hearts were so hardened that even all the good miraculous works they witnessed meant nothing to them. A hardened heart is a foolish one, while an open heart, a wise one. Being open-hearted does not risk losing your heart; it simply lets you discern right from wrong. If what you observe is truly false, you can always reject it. On the other hand, a hardened heart is a closed, judgmental heart, already set to dismiss what might be the truth. It becomes a danger to one's own soul.
