GF writes: “I used to be a fan of Brian Tracy, Joseph Murphy and Terry Cole Whittaker untiI I started recognizing that their teachings seem to deviate from bible principles although their books quote Bible verses to make their point. So I stopped reading their books. I recently purchased a book called The 4:8 Principal, the Secret of a Joy Filled Life by Tommy Newberry. Would you please advise if his motivational teachings are aligned with biblical teachings.”
