A.W. Tozer emphasizes that the most urgent need for the church today is a revival that leads to a reformed and purified body of believers. He argues that the quality of Christians is more crucial than the quantity, as each generation's spiritual state directly influences the next. To improve the church, members must first seek personal moral and spiritual growth, recognizing that the church reflects its individual members. Tozer highlights the challenge of genuine improvement, as it requires personal sacrifice and commitment rather than mere academic discussion.
