Continuing his contrast between the people in Gideon with those in Zarahemla, he notes that the people of Gideon “are in the path which leads to the kingdom of God.” The undeclared contrast is to those in Zarahemla who were in the very opposite path.
As with his sermon in Zarahemla, Alma references the final judgment between good and evil. The path of righteousness leads to God. One in that path does not turn “from that which is right to that which is wrong.” Thus, those in that path come clean to God.
Those who do not, come filthy to God and “shall remain in his filthiness.” The opposition of clean and filthy becomes another version of the opposition between good and evil. Only good and clean will enter into the kingdom of God.
