It seems to me that the "feel good" Christianity ..as I call it the "rodney king " school of theology..has compromised the message.
Many people become Christians because they want their carnal life problems solved..They could never give the testimony of a Bonhoeffer or Nee (no matter how you feel about their doctrine)
We are told God allows the Wheat and Tares to grow together untill the end..that is true in the churches too.
As for Mac Arthur being "harsh" ..I do not ~think~ his is a ministry aimed at making radio conversions with phony sinners prayers..He is about doing what the church is to do..equip the saints
He is straight foreward ..that is hard to hear in a feel good church
He is a solid teacher..IMHO
