SimchaMinute by Rabbi Avigdor Miller
If the Yam Suf would split open today, the Hebrew university would send a team of scientists to investigate the seismic disturbance — some earthquake! — and the New York Times would have a write up about it, various theories, and that’s where it would end.
Hashem at that time was able to give them this miracle because they were people who could appreciate it. And today it would be a waste of a good miracle. — Preface to Purim (#302)
