One Second of Suffering

In regards to accepting suffering with love, Rav Moshe Leib of Sassov zy”a (quoted in Mishnas HaRamal, Sichos Kodesh ) said, “The suffering I experienced in the past is over. I don’t feel that pain at all anymore. As far as future suffering, one must believe and hope that Hashem will save him and prevent that from happening. Thus, the only thing one has to worry about is the current moment. And that only lasts for a second! Why can’t a person accept one second of suffering sent from Hashem?”
