"Amen, amen, I say to you, unless one is born from above"

Indeed they gathered in this city against your holy servant Jesus whom you anointed, Herod and Pontius Pilate, together with the Gentiles and the peoples of Israel, to do what your hand and your will had long ago planned to take place.

-- Acts 4:23-31

To God, all moments of time are present in their immediacy. When therefore he establishes his eternal plan of "predestination", he includes in it each person's free response to his grace: "In this city, in fact, both Herod and Pontius Pilate, with the Gentiles and the peoples of Israel, gathered together against your holy servant Jesus, whom you anointed, to do whatever your hand and your plan had predestined to take place." For the sake of accomplishing his plan of salvation, God permitted the acts that flowed from their blindness.

"Amen, amen, I say to you, unless one is born from above, he cannot see the Kingdom of God."

-- Jn 3:1-8

In his Passover Christ opened to all men the fountain of Baptism. He had already spoken of his Passion, which he was about to suffer in Jerusalem, as a "Baptism" with which he had to be baptized. The blood and water that flowed from the pierced side of the crucified Jesus are types of Baptism and the Eucharist, the sacraments of new life. From then on, it is possible "to be born of water and the Spirit" in order to enter the Kingdom of God.

See where you are baptized, see where Baptism comes from, if not from the cross of Christ, from his death. There is the whole mystery: he died for you. In him you are redeemed, in him you are saved.

-- CCC 1225

The Lord himself affirms that Baptism is necessary for salvation. He also commands his disciples to proclaim the Gospel to all nations and to baptize them. Baptism is necessary for salvation for those to whom the Gospel has been proclaimed and who have had the possibility of asking for this sacrament. The Church does not know of any means other than Baptism that assures entry into eternal beatitude; this is why she takes care not to neglect the mission she has received from the Lord to see that all who can be baptized are "reborn of water and the Spirit." God has bound salvation to the sacrament of Baptism, but he himself is not bound by his sacraments.
