In today's episode, Dr. Beach explores John Calvin’s thoughts on the role of the Holy Spirit in uniting believers to Christ through faith. He touches on the necessity of being "in Christ" to receive salvation's benefits, the nature of true faith as a firm knowledge of God's benevolence, and the struggle between faith and doubt in the believer's life. He also examines Calvin's critique of certain Catholic doctrines and emphasizes that genuine faith, while sometimes weak, ultimately triumphs through God's grace, highlighting Calvin's emphasis on resting in Christ's work rather than one's own efforts for assurance of salvation.
