A.W. Tozer emphasizes the importance of the apostolic method of teaching, which combines instruction with exhortation, as exemplified in the writings of Paul. He highlights that the faithful men of old provided scriptural reasons for Christian actions, encouraging believers to respond with personal faith and godliness. Tozer points out that the message of Christ's supremacy over Moses and the angels serves as a foundation for the exhortation to love and pray for one another. This method of teaching calls for immediate and unreserved action based on the truths of Scripture. The sermon encourages believers to understand the reasons behind their faith and to act accordingly.
