Unless one ultimately finds God's blessing of locating a pastor who understands the Greek and Hebrew, many of the things they will decipher from the likes of the KJV and modern translations will leave them dull, yet dogmatic in many ways.
Jesus warned that there is a broad and wide way (mainstream, herd thinking) that leads to destruction. Only a few will find it. Only a few pastors are intelligent and skilled enough to exegete for their hearers. It all works out as Jesus said it would. To argue over a translation like the KJV, or NIV? Is dumb. Some truth can be had. But way too much was lost in the translation.
