Even though the Lamanites might be angry with the Nephites on account of their religion, Moroni declares that it is precisely their religion that has allowed this victory. God has been with them, and Moroni declares that to Zerahemnah. Why does Moroni declare this to Zarahemnah? Moroni is attempting to have Zerahemnah declare a peace at to swear to leave the Nephites alone. If Nephi can convince the Lamanites that God has been behind their victory, then they might assume that any future attacks would have the same result.
