Musar zu Hoschea 7:13

But when a man accepts the reproof of God, improves his ways and his plans, it is fitting for him to rejoice about the afflictions - for they help him with lofty accomplishments. So he should thank God, may He be elevated, for them. As it is stated (Psalms 116:13), "I raise the cup of deliverance and invoke the name of the Lord"; and it is [also] stated (Psalms 116:3-4), "I came upon trouble and sorrow. And I invoked the name of the Lord." And our Rabbis, may their memory be blessed, said in the Sifrei, "Rabbi Eliezer ben Ya'akov says, 'The whole time a person is dwelling in tranquility, his iniquities are not atoned at all for him; but through afflictions, he becomes acceptable to the Omnipresent.'" And it is stated (Proverbs 3:12), "For whom the Lord loves, He rebukes, as a father the son whom he favors." Its explanation is, like a father to a son, so too does God desire the one He rebukes and who accepts His reproof - in the same way a father desires his son after the rebukes. And it can also be explained, like a father rebukes the son that wants it; but he does not rebuke the sons about whom he has given up, and for which rebuke will not be effective. And it is stated about people that do not recognize the good of rebuke and its purpose (Hosea 7:13), "I was their Redeemer; yet they have plotted treason against Me." And it is [also] stated (Hosea 7:15), "I braced, I strengthened their arms; and they plot evil against Me!" And it is [further] stated (Hosea 11:3), "I have pampered Ephraim, taking them in My arms; but they have ignored My healing care."
