All need wisdom carefully to search out the mystery of iniquity that figures so largely in the winding up of this earth’s history…. In the very time in which we live, the Lord has called His people and has given them a message to bear. He has called them to expose the wickedness of the man of sin who has made the Sunday law a distinctive power, who has thought to change times and laws, and to oppress the people of God who stand firmly to honor Him by keeping the only true Sabbath, the Sabbath of creation, as holy unto the Lord. TM 117.5
The sins of Babylon will be laid open. The fearful results of enforcing the observances of the church by civil authority, the inroads of Spiritualism, the stealthy but rapid progress of the papal power,—all will be unmasked. By these solemn warnings the people will be stirred. Thousands upon thousands will listen who have never heard words like these. In amazement they hear the testimony that Babylon is the church, fallen because of her errors and sins, because of her rejection of the truth sent to her from Heaven. Great Controversy published 1888.
Not only do we need to expose wickedness, but we also need to know the power of God to save!
