My brother, Dave, was told by Mormon missionaries to pray and ask God to confirm if Joseph Smith and the Book of Mormon was truly of God, the confirmation being a “burning in your breast” — a subjective feeling that these things were true.
Dave prayed the prayer and got the feeling, not knowing about II Corinthians 11:14, that Satan disguises himself as an angel of light, counterfeiting the ministry of the Holy Spirit. Dave reversed the order, putting feelings before the already-revealed facts of the Word.
The result? Thirteen years in bondage to a lie — and the loss of his family once he came to a knowledge of the truth and chose to leave the Church of Jesus Christ of Latter-Day Saints.
This is why every subjective experience must measure up to the objective teaching of the Word of God. In other words: our feelings must line up with the facts.
