Joseph Smith Translation 1,000x Better than Other Bibles

Ensign, June 1999 pg 15; “In the words of Elder Bruce R. McConkie (1915–85) of the Quorum of the Twelve Apostles, “The Joseph Smith Translation, or Inspired Version, is a thousand times over the best Bible now existing on earth.”” – Andrew C. Skinner

2 Timothy 3:16-17; “All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: 17 That the man of God may be perfect, throughly furnished unto all good works.”

How is the Bible not sufficient when God tells us it is?
