When Jesus had received the wine, he said,
"It is finished";
and he bowed his head and handed over the spirit.
Gospel of John 19:30
The sixth word is Jesus' recognition that his suffering is over and his task is completed. Jesus was obedient to the Father and gave his love for mankind by redeeming us with His death on the Cross.
When Jesus died, He "handed over" the Spirit.
Jesus remains in control to the end, and it is He who handed over his Spirit. One should not miss the double entendre here, for this may also be interpreted as His death brought forth the Holy Spirit. The Gospel of John gradually reveals the Holy Spirit. Jesus mentions living water in John 4:10-11 when he met the Samaritan woman at the well, and during the Feast of Tabernacles refers to living water as the Holy Spirit in 7:37-39. At the Last Supper, Christ announced he would ask the Father to send "another Advocate to be with you always, the Spirit of truth" (14:16-17). The word Advocate is also translated as Comforter, Helper, Paraclete, or Counselor. "But the Advocate, the Holy Spirit, whom the Father will send in my name, will teach you everything, and remind you of all that I have said to you" (14:26). The symbolism of water and the Holy Spirit become more evident in John 19:34: "But one of the soldiers pierced his side with a spear, and immediately there came out blood and water." The piercing of his side fulfilled the prophecy in Zechariah 12:10: "They will look on me whom they have pierced." The piercing of Jesus' side prefigures the Sacraments of Eucharist (blood) and Baptism (water), as well as the beginning of the Church.
