Wherever persons of different stamps of character are associated together in any institution, there must be firm, determined effort to keep the institution pure, elevated, noble, that the wicked one shall not succeed in demoralizing it. There are unsanctified elements to meet, and if all are striving to do right and work righteousness and to be a blessing to each other, the objectionable features will be overcome. This world is not heaven. In our duties of life we are not associating with angels, but with human beings who are liable to err.—Manuscript 41, 1900. MM 211.4
