Titus 3:6 whom he poured out on us generously through Jesus Christ our Saviour
Titus 3:5 refers to the Holy Spirit and his work of renewing the believer. In the verse following Paul speaks of the Spirit and develops the idea of his being poured out on believers and not just poured out but richly or generously poured out. The reference is no doubt to the initial outpouring at Pentecost and to the way he is poured out at the beginning of the Christian life on each individual believer when he is baptised by the Spirit or born anew. It reminds us of Jesus' statement in John 4:14 that the water I give them will become in them a spring of water welling up to eternal life. We must not miss that through Jesus Christ our Saviour either which further links what Paul says and what John reports. It is because of Christ and all he has done as our Saviour that the Spirit has been poured out. In John 7:38, 39 which refers again to rivers of living water flowing from within. John clarifies - By this he meant the Spirit, whom those who believed in him were later to receive. He clearly links the atonement and what followed with the pouring out of the Spirit when he says Up to that time the Spirit had not been given, since Jesus had not yet been glorified. The moment a minister forgets about the work of the Spirit he is finished.
