Corianton had bought into the wrong "plan" (as had Zeezrom in Alma 12), and thus Alma's sermon, in order to turn his son back onto the true path, needed to state the totality of the true plan. Even if someone isn’t aware of this tenfold thread, the subconscious effect of its tenfold repetition allows the spirit to gather momentum to a very satisfying conclusion and convincing admonition. Alma's words had a very salutary effect on Corianton. This emphatic element may be one of the reasons why these words left such an indelible impression on his son and still leave such a powerful impact on readers today.
