Rev 21, 5-6 Behold, I make all things new

(Rev 21, 5-6) Behold, I make all things new

[5] The one who sat on the throne said, "Behold, I make all things new." Then he said, "Write these words down, for they are trustworthy and true." [6] He said to me, "They are accomplished. I (am) the Alpha and the Omega, the beginning and the end. To the thirsty I will give a gift from the spring of life-giving water.

(CCC 694) Water. The symbolism of water signifies the Holy Spirit's action in Baptism, since after the invocation of the Holy Spirit it becomes the efficacious sacramental sign of new birth: just as the gestation of our first birth took place in water, so the water of Baptism truly signifies that our birth into the divine life is given to us in the Holy Spirit. As "by one Spirit we were all baptized," so we are also "made to drink of one Spirit" (1 Cor 12:13). Thus the Spirit is also personally the living water welling up from Christ crucified (Jn 19:34; 1 Jn 5:8) as its source and welling up in us to eternal life (Cf. Jn 4:10-14; 7:38; Ex 17:1-6; Isa 55:1; Zech 14:8; 1 Cor 10:4; Rev 21:6; 22:17). (CCC 1137) The book of Revelation of St. John, read in the Church's liturgy, first reveals to us, "A throne stood in heaven, with one seated on the throne": "the Lord God" (Rev 4:2, 8; Isa 6:1; cf. Ezek 1:26-28). It then shows the Lamb, "standing, as though it had been slain": Christ crucified and risen, the one high priest of the true sanctuary, the same one "who offers and is offered, who gives and is given" (Rev 5:6; Liturgy of St. John Chrysostom, Anaphora; cf. Jn 1:29; Heb 4:14-15; 10:19-2). Finally it presents "the river of the water of life… Flowing from the throne of God and of the Lamb," one of most beautiful symbols of the Holy Spirit (Rev 22:1; cf. 21:6; Jn 4:10-14).
