One of the problems with big events is that they're big events. That is, they happen on such a massive scale that their actual impact on us isn't all that much. Like going to a ball game, it's fun while we're there, but afterwards (unless we say something) nobody knows we were ever there.
Given all of the build up to it (Lent) and what happens right before it (Maundy Thursday, Good Friday), not to mention Easter itself, it's all too easy for us to treat Easter like just another big event.
Which is one of the reasons for the readings, and for Divine Mercy Sunday itself. To make sure we don't forget that this one's personal.
Because Easter isn't just another big event.
More on this tomorrow.
