"A succession of showers from the living waters has come to you at Battle Creek. Each shower was a consecrated inflowing of divine influence; but you did not recognize it as such. Instead of drinking copiously of the streams of salvation so freely offered through the influence of the Holy Spirit, you turned to satisfy your soul thirst with the polluted waters of human science. The result has been parched hearts in the school and in the church. Those who are satisfied with little spirituality have gone far in unfitting themselves to appreciate the deep movings of the Spirit of God.... CT 358.2"
"He that believeth on me, as the scripture hath said, out of his belly shall flow rivers of living water."
The EGW passage uses the imagery of "showers from the living waters" and "streams of salvation" to describe the influence of the Holy Spirit, which is a clear parallel to the "rivers of living water" flowing from believers in John 7:38. Both passages connect spiritual fulfillment with divine influence.
