"They say that prayer and who knows if it worked. They don't have communion."But there are "tells" ... for evangelicals.
For instance, Bible teacher Kay Arthur routinely quotes 2 Tim. 2:15, according to the King James, to impart that if one does one's homework and studies one's Bible, one has shown oneself to be approved (acceptable) unto God.1
However, look at 2 Tim. 2:15 in any modern English translation and you'll see Arthur makes convenient use of it. More than that, by relying on the King James only, she effectively masks a verse that affirms human effort to some degree: "Do your best ..." (NIV)
1 Like on the Matthean beatitudes, interpretation is inverted: it's not "Do this and be blessed," rather it's "The blessèd do this (by the grace of God)."
