A Christian in whom the Holy Spirit dwells is not exempt from having to experience struggle, temptations, disorderly desires, rebellious feelings… [the difference is that all these things come] upon him against his will.’ They are on the surface. Yet there is a ‘peace in the depth of their hearts. That is like a deep-ocean current always flowing steadily regardless of the wind and the waves on the surface.” –Father Raniero Cantalamessa

Rivers of living water

On the last and greatest day of the festival, Jesus stood and said in a loud voice, “Let anyone who is thirsty come to me and drink. Whoever believes in me, as Scripture has said, rivers of living water will flow from within them.” By this he meant the Spirit, whom those who believed in him were later to receive. Up to that time the Spirit had not been given, since Jesus had not yet been glorified.
