אות-לז

Most of the falls of a person come from the fact that he has already been aroused several times toward Hashem and has fallen from this. But in truth it is the opposite — for even one who has sinned all his days and was never aroused to teshuvah at all, if he eventually returns, it is forgiven — as our sages of blessed memory taught. How much more so one who has been aroused several times and has turned away again, and so it was many times — such a person certainly has hope, and certainly it is easier for him to return to Hashem in truth. For leis retusa tava d'is'abid — no good will is ever lost. (ibid., Halacha 7, Ois 7)
