What's in error is your interpretation or whoever you are listening to. The Bible was written over a 1500 year span, in different locations, by men all from different walks of life. They were God inspired, the Holy Ghost used them as ink pens. And at times they did not even understand their own writing. And yet the Bible books all have unity, scripture proves scripture. It takes a real study of the Bible with a seeking heart, faith and acceptance of Jesus Christ as Savior to have spiritual discernment of the scriptures. The natural man is not truth seeking nor spiritually discerned, and so his interpretation of the scriptures is in error.
