Let the Spirit be lacking, and there may be wisdom of words, but not the wisdom of God; the powers of oratory, but not the power of God; the demonstration of argument and the logic of the schools, but not the demonstration of the Holy Spirit, the all-convincing logic of His lightning flash, such as convinced Saul before the Damascus gate. When the Spirit was outpoured the disciples were all filled with power from on high, the most unlettered tongue could silence gainsayers, and with its new fire burn its way through obstacles as flames fanned by mighty winds sweep through forests.
