Without a doubt, pornography is addictive and is poison. Had I learned early in my life to apply the power of self-mastery, I would be a member of the Church today. There is no such doctrine in this Church. This may sound subtly appealing, but it is in fact pernicious and a false concept. Its objective is to persuade us that we can consciously and deliberately transgress with the forethought that quick repentance will permit us to enjoy the full blessings of the gospel, such as temple blessings or a mission.
True repentance can be a long, painful process.
This is because all of our covenants must not only be received through ordinances but to be eternal must also be sealed by the Holy Spirit of Promise. This divine stamp of approval is placed upon our ordinances and covenants only through faithfulness. The false idea of so-called premeditated repentance involves an element of deception, but the Holy Spirit of Promise cannot be deceived. Some people wear masks of decency and outward righteousness but live lives of deception, believing that, like Dr. Jekyll, they can live a double life and never be found out. In the Book of Mormon we read the account of Corianton, who went on a mission to the Zoramites with his father and brother.
