As Christians we have a GREAT base of power.  Jesus spoke of it as "the comforter", "the promise of the Father", and to be "endued with power from on high."
At Pentecost those gathered received the result of this promise..and in fulfillment of that promise, they spoke in tongues!!
What a joy that we can learn to operate all nine of these manifestations as listed in I Cor. 12:7-10.  God is good!!
