The history of Achan teaches the solemn lesson that for one man’s sin the displeasure of God will rest upon a people or a nation till the transgression is searched out and punished. Sin is corrupting in its nature. One man infected with its deadly leprosy may communicate the taint to thousands. Those who occupy responsible positions as guardians of the people are false to their trust if they do not faithfully search out and reprove sin. Many dare not condemn iniquity, lest they shall thereby sacrifice position or popularity. And by some it is considered uncharitable to rebuke sin. The servant of God should never allow his own spirit to be mingled with the reproof which he is required to give; but he is under the most solemn obligation to present the Word of God, without fear or favor. He must call sin by its right name. Those who by their carelessness or indifference permit God’s name to be dishonored by His professed people, are numbered with the transgressor,—registered in the record of heaven as partakers in their evil deeds....
 The love of God will never lead to the belittling of sin; it will never cover or excuse an unconfessed wrong. Achan learned too late that God’s law, like its Author, is unchanging. It has to do with all our acts and thoughts and feelings. It follows us, and reaches every secret spring of action. By indulgence in sin, men are led to lightly regard the law of God. Many conceal their transgressions from their fellow men, and flatter themselves that God will not be strict to mark iniquity. But His law is the great standard of right, and with it every act of life must be compared in that day when God shall bring every work into judgment, with every secret thing, whether it be good or evil. Purity of heart will lead to purity of life. All excuses for sin are vain. Who can plead for the sinner when God testifies against him? (The Signs of the Times, April 21, 1881).

 Have you considered why it was that all who were connected with Achan were also subjects of the punishment of God? It was because they had not been trained and educated according to the directions given them in the great standard of the law of God. Achan’s parents had educated their son in such a way that he felt free to disobey the Word of the Lord, the principles inculcated in his life led him to deal with his children in such a way that they also were corrupted. Mind acts and reacts upon mind, and the punishment which included the relations of Achan with himself, reveals the fact that all were involved in the transgression (Manuscript 67, 1894).
