Musar zu Pirkei Avot 3:12

The third thing that can stir the heart to repentance is when he hears the chastisement of the wise and of those who reprove him, and this arouses his heart to repent, and he receives upon himself all the words of these rebukes. From the time that he accepts them, this man earns great merit, and in a short space of time he has gone forth from darkness to light, and he has gained reward and merit for all of the commandments and all of the chastisements, inasmuch as he has resolved to receive them upon himself. And happy is he who receives this upon himself, for he has won merit in a brief moment. And thus did our Sages, of blessed memory, say "And the children of Israel went and did." Now had they already done this (i.e., prepared the Passover)? Surely, they did not do so until the fourteenth day of the month! But when they took it upon themselves to do it, Scripture ascribes it to them as though they had already done it" (Mechilta on Exodus 12:28). And thus did our Sages say, "All whose deeds are greater than his wisdom, his wisdom will endure" (Aboth 3:12). As it is said, "We will do and we will hear!" (Ex. 24:7).
