Florida Christadelphian Bible School (2001)

This series takes us into the book of Acts to explore the energy, conviction, and faith of those early believers who were accused of “turning the world upside down.” Through historical context, scriptural study, and practical application, these classes encourage us to see how the same gospel message can still challenge and transform lives today. Each talk examines key events, individuals, and lessons from the first-century ecclesias, showing how their zeal and unity can inspire and guide our efforts now.

The Flame That Would Not Be Quenched

This opening class looks at the unstoppable growth of the early ecclesia despite persecution and opposition. We see how the apostles’ courage and steadfast preaching kept the flame of truth alive, and how their faithfulness set an enduring pattern for us to follow. The emphasis is on holding firmly to the gospel and trusting in God’s power to sustain His work.

Preaching Boldly in the Name of Jesus Christ

Here Bro. David focuses on the bold witness of the apostles, who proclaimed the name of Jesus without compromise. The lesson draws attention to the spiritual strength that comes from prayer, reliance on scripture, and the support of fellow believers. We are challenged to be equally fearless in sharing our faith today, regardless of circumstances.

The Struggle for Unity

This class examines the tensions and disputes that arose in the early ecclesias, and how they were addressed through humility, wisdom, and the guidance of God’s spirit. It calls us to protect and nurture unity, recognizing that love and mutual respect are vital for the gospel to flourish within our communities.

Problems Within and Without

Turning to the pressures faced by the first believers, both from internal weaknesses and external threats, this session explores the importance of discernment, steadfastness, and mutual care. The examples from Acts remind us that God can use even challenges to strengthen His people when they remain faithful to Him.

Why Persecutest Thou Me?

This talk follows the dramatic conversion of Saul of Tarsus, highlighting the transforming power of God’s calling. We are reminded that no one is beyond the reach of the gospel, and that genuine repentance leads to a life of dedicated service. Saul’s example inspires us to embrace our calling with sincerity and zeal.

Ecclesias Then and Now

In the final class, the focus shifts to practical lessons for today’s ecclesias, drawing from the principles and practices of the first century. Special attention is given to the role of prayer, the responsibilities of arranging brethren, and the shared mission of all members. We are encouraged to rekindle the enthusiasm and dedication of the early believers in our own service to God.
