Fear is a major factor that quenches the Spirit. Various groups of people generate fear against the operation of the gifts of the Spirit. Preachers and teachers of the Bible who are dedicated to the preservation of the truth of the Bible and Christian character, oppose many of the operations of the Spirit, because they see the rampant abuse of the gifts of the Spirit. Their concerns are understandable, but it is impossible for the Body of Christ to exist without the gifts of the Spirit.
Mistakes and limitations are possible in ministry, but the fear of these should not drive us to quench the Spirit. Love is the key to overcoming the fear that militates against the operations of the Spirit. The love of God generates faith in God and trust for others who truthfully seek to bring the Word of God and deliverance to believers.
