Over the period of 10 weeks, as we pray and allow the Holy Spirit to do his work, giving people the opportunity to respond, we are, in effect, making a continuous appeal to their wills. Far from dwindling away through the period covered by the book of Acts, this spiritual dynamic continued. Paul went in to see him and, after prayer, placed his hands on him and healed him. All the way through we see the dynamic effect of the coming of the kingdom of God accompanied by conversions, miraculous signs, healings, visions, tongues, prophecy, raising the dead, and casting out evil spirits. The same God is at work today among us.
Evangelism can still be dynamic and effective.
However, it did not end there. The filling of the Holy Spirit is not a one-time experience. Billy Graham asked to see Olford privately and Olford expounded the fullness of the Holy Spirit in the life of a believer. This will revolutionize my ministry. One of the keys to Alpha is having a team of Spirit-filled people using every gift they possess to lead others to Christ.
