(1) [Who has reached] complete Teshuvah? A person who confronts the same situation in which he sinned when he has the potential to commit [the sin again], and, nevertheless, abstains and does not commit it because of his Teshuvah alone and not because of fear or a lack of strength.
For example, a person engaged in illicit sexual relations with a woman. Afterwards, they met in privacy, in the same country, while his love for her and physical power still persisted, and nevertheless, he abstained and did not transgress. This is a complete Baal-Teshuvah. This was implied by King Solomon in his statement [Ecclesiastes 12:1] "Remember your Creator in the days of your youth, [before the bad days come and the years draw near when you will say: `I have no desire for them.'"]
If he does not repent until his old age, at a time when he is incapable of doing what he did before, even though this is not a high level of repentance, he is a Baal-Teshuvah.
Even if he transgressed throughout his entire life and repented on the day of his death and died in repentance, all his sins are forgiven as [Ecclesiastes, op. cit.:2] continues: "Before the sun, the light, the moon, or the stars are darkened and the clouds return after the rain..." - This refers to the day of death. Thus, we can infer that if one remembers his Creator and repents before he dies, he is forgiven.
Know this: you must judge every person favorably. Even for a completely wicked person, you must search for and find in them some small part which is good, that small part that is not wicked. And so you can judge them favorably by considering this small part that you have found. And by truly raising them up by this favorable judgment, it becomes possible that they will do teshuvah. …
So too, everyone must find [the good part] of themselves! … And by searching and finding in themselves some small part that is still good, thereby you can switch from judging yourself as guilty to judging yourself favorably, and can do teshuvah.
