Samuel Logan Brengle explores how Jesus trained Paul through trials, struggles, and divine revelations, emphasizing that Paul's journey was marked by suffering and obedience to faith. He highlights that Paul's transformation from a persecutor to an apostle involved deep personal struggles and a reliance on God's guidance, particularly during his time in solitude. Brengle illustrates that Paul's experiences were not just for his own growth but served to teach the entire Church about faith, suffering, and the nature of God's love. The sermon underscores the importance of learning through trials and the necessity of being trained by Jesus in the school of suffering. Ultimately, Brengle encourages believers to embrace their own journeys of faith, trusting in God's purpose and strength.
