If one had mostly merits and a minority of Aveiros, they collect from him (he is punished) in this world for his minority of light Aveiros, so he will receive his full reward in the world to come.

Idolatry and Arayos - R. Yonah and R. Yosah argue about them. One said that they are light [like other Aveiros], and one said that they are severe (one who transgressed then is considered to be mostly Aveiros).

Question: What is the case? If he repented, nothing stands in front of Ba'alei Teshuvah (to deprive them of reward)!

Answer: Rather, we discuss one who did not repent, and he died amidst Kares.

If one had mostly Aveiros and a minority of merits, they give to him in this world reward for his light Mitzvos, so he will receive his full punishment in the world to come.

If one had mostly merits, he inherits Gan Eden. If he had mostly Aveiros, he inherits Gehinom.

(R. Yosi ben Chaninah): If [his Aveiros and merits] were equal - it does not say 'Nosei Avonos', rather, "Nosei Avon" - Hash-m removes one Aveirah, and the merits outweigh.
