In this episode, we explore why sound doctrine is essential for the Christian life. Drawing from Samuel Willard’s "A Complete Body of Divinity" (1726), we reflect on the necessity of holding fast to the truth, testing every teaching by Scripture, and guarding against error that leads to spiritual ruin. This is a call to love the truth, live the truth, and be willing to suffer for the truth—because to be careless about doctrine is to be careless about Christ Himself.
