MacArthur makes many valid points...HOWEVER, he also displays a total ignorance and misunderstanding in many things he says. If I follow him word for word, many of my non-charismatic friends, who are followers of MacArthur would now be considered suspect as trustworthy. It is impossible for MacAuthur to have heard from God on anything he has printed...for basically, he says 'we know longer hear from God by inspiritation etc.' Again, I do agree with him exposing error...but I must also say, he has exposed himself as being in error as well.
My biggest issue is his use of the word: 'all charismatics'...if there is one problem child in his fellowship...then all members of his fellowship should be labeled as 'problem children and unreliable as well.'
Having been raised in a Pentecostal ministering family and experienced most if not all of the subjects MacArthur addresses in Charismatic Chaos I could not recommend a better read, other than God's Word, which he leans on heavily to validate the cessationist view of the gifts of the Spirit he endorses.
Subjective experiences to validate understanding of God is not safe or Biblical. If your desire is to know God as He reveals Himself in His Word but are confused about spiritual experiences and how they relate to your understanding of God this is a must read.
It is written to be understood and carefully respectful of people's feelings. Anyone offended, in my opinion, is not ready for Biblical truth on the matter and has a skewed and man-centered view of the Holy Spirit and His work in the life of the Church. His work is to testify of the Son and Glorify the Father, not man.
