Rhetorical: Alma has made it abundantly clear that there is no acceptance for those who have committed the particular sins he has mentioned. Here is specifically notes that there is acceptance for those who repent of them. This is an important point, not only for his audience, but for all of us. There are sins which preclude us from the benefits of heaven. However, we are able to repent, and upon repentance, those benefits are once again open to us. It is the sin, not the person, that is precluded. If we sincerely repent, the Lord says: "I will receive you."
