In this sermon, the speaker discusses the role of feelings in spiritual warfare and the importance of faith in God's word. Using the story of Deborah and Jael from Judges 4-5, the speaker explores the destructive nature of uncontrolled emotions and the power of the word of God to destroy strongholds. The speaker encourages believers to take every thought captive to obey Christ and to use the weapons of spiritual warfare, including the helmet of salvation and the sword of the spirit, which is the word of God.
