Interesting interview with a Christian pop singer and her experience in a progressive church where the pastor used insidious methods to change the church member's beliefs.
If people follow closely what they are being taught by 'people' and compare that to the bible (Gods Word) they will often find huge discrepancies. One big example is Gods personal name ( יהוה ). His name is used more that any other name in the bible (almost 7,000 times), but for some reason it has been removed or changed in many versions of the bible we see today. If you do not know what the Tetragrammaton is, you can read more about that in many articles including this one: The Divine Name in the Hebrew Scriptures
If Christians can't agree not to change the bible regarding something as fundamental as Gods personal name, what hope is there for them to be accurately taught other bible truths?
