Strange Fire launched Wednesday morning with John MacArthur explaining the basis and the need for the conference. Starting with the story of Nadab and Abihu (Leviticus 10), he described the dangers of fraudulent worship and the vital need for discernment, the lack of which is "the biggest problem in the church today." The purpose of the conference then is to help the church discern the truth about the charismatic movement, which he said has made no contribution to biblical clarity, interpretation, or sound doctrine. John closed by highlighting the true work of the Holy Spirit—conforming believers to Christlikeness. Working through the life of Christ, he showed that the relationship between Jesus and the Holy Spirit is the model for the Spirit's work in the life of every believer. Put simply, the Spirit's work is to mature, sustain, empower, fill, and perfect us toward the likeness of our Savior.
