Musar do Amosa 4:6

Great is repentance, for it brings man near to the Divine Presence, as it is said, "Return, O Israel, unto the Lord thy God" (Hos. 14:2; and see Yoma 86a). And it is said, "Yet have ye not returned unto Me, saith the Lord God" (Amos 4:6). And it is said, "If thou wilt return, O Israel, saith the Lord, Yea, return unto Me" (Jer. 4:1), that is to say, "If you will return with repentance, you will cleave to me." Repentance brings near those who are far off. Last night this man was hated before God, Blessed be He, — defiled, far removed, an abomination — but today he is loved and precious and near and dear. And so you find this clearly shown in the language with which the Holy One, Blessed be He, thrusts away the sinners and the language with which He receives those who are repentant, whether it be one person or whether it be many, as it is said, "And it shall come to pass that instead of that which was said, unto them 'Ye are not my people', it shall be said unto them 'Ye are the children of the living God' " (Hos. 2:1).
