Smith Wigglesworth emphasizes the significance of desiring spiritual gifts, particularly the gift of tongues, as a means of divine communication with God. He illustrates how speaking in tongues allows believers to edify themselves and intercede according to God's will, sharing a testimony of Willie Burton's miraculous recovery through prayer in tongues. Wigglesworth encourages believers to pursue the gifts of the Spirit with fervor, highlighting that while tongues are for personal edification, prophecy serves to build up the church. He stresses the importance of understanding and interpreting tongues for the benefit of the congregation, urging believers to remain steadfast in their pursuit of spiritual gifts.
