If there ever was a group of people who felt ill-prepared for the monumental mission of world evangelization, it would have been the disciples of Jesus at the end of the Gospels. Anxious, frazzled, frightened, and leaderless, this group of 120 followers (Acts 1:15) were in no position to take the world by storm. Yet, by the end of the first day of the birth of the church, this tiny movement had grown to three thousand followers of Christ, and increased exponentially by the end of the second chapter of the book of Acts (“…And the Lord added to their number daily those who were being saved.”) So, what or WHO made the difference? How did this small group of timid believers become a catalyst for the spreading of the Gospel throughout the world? What happens to us and our communities when the promised Holy Spirit of God indwells and fills our lives?
