It is always through the process of doing his duty that man is gradually changed, and it is through this process that he demonstrates his loyalty. As such, the more you are able to do your duty, the more truths you shall receive, and so too shall your expression become more real, so too shall your expression become more real. Those who merely go through the motions in doing their duty and do not seek the truth shall be eliminated in the end, shall be eliminated in the end, for such men do not do their duty in the practice of truth, and do not practice truth in the fulfillment of their duty. Such men are those who remain unchanged and will be cursed. Not only are their expressions impure, but what they express is nothing but wickedness.
from “The Difference Between the Ministry of the Incarnate God and the Duty of Man” in The Word Appears in the Flesh
