The early church spread with remarkable speed, impelled by joy, urgency, profound compassion, and the day-to-day experience of working in the power of the Holy Spirit. Despite opposition at all levels, the first Christians expressed their love and wonder in acts of kindness, worship, and their eagerness to share the wholescale transformation that attends the profound experience of conversion. Gavin and Anne Calver explore what this extraordinary historical account means for believers today, considering themes including: The Holy Spirit in the life of the church; taking risks; living together in the power of the Spirit; works and wonders; hearing from God; responding to the call of God; miracles then and now.
