The fundamental problem of traditional Christian churches is that we are running out of spiritual energy. I take spiritual energy as the sum of the time and dollars church members give to their congregation out of their Christian commitment. Many congregations have drifted into the mindset of the many social organizations in our society. Those, too, are in steep decline. It is the fellowship of the Holy Spirit that makes congregations distinctly Christian. To regain spiritual energy we need to increase our understanding of how the Spirit works today.
