In this century, relationships between and among the different religious traditions of the world will become more and more important as we strive to promote a "dialogue" of cultures instead of a "conflict of civilizations." How Pentecostals will fit into this picture is still a mystery. Will their zeal for proselytism make it more difficult to find common ground with their neighbors of other faiths, especially in Africa and Asia? Or will they begin to recognize, as some already are (including the prolific young Pentecostal theologian Amos Yong), that the same Spirit that touches their hearts may also be speaking to those who do not share their theological beliefs?
In any case, Martin Marty may well have been right when he wrote that the future of Christianity—in say 50 years—may look more Pentecostal than anything else.
