The Lord teaches true doctrine to a people that only desire the truth in part, yet some of those same doctrines are no longer believed by the modern LDS church. The Lord teaches his approved method for determining whether a spirit is from him or not, a method which is no longer taught by the modern church. And the Lord teaches how to properly teach the gospel, a method which has been deliberately avoided by the modern church’s missionary program for almost 100 years.
