In Day 343 of The Bible in a Year podcast, Fr. Mike Schmitz focuses on Acts 22, where Paul shares his transformation from a persecutor of Christians to an evangelist. This invokes a reflection on how God uses our past experiences to empower our ministries today. The episode emphasizes the significance of being cheerful givers, rooted in God's grace, alongside the idea that the primary credential for ministry is being called by God. Fr. Mike also draws from readings in 2 Corinthians, highlighting the importance of generosity and the transformative power of God's Word in believers' lives.
