Well, OK, we certainly can’t prove anything by scripture alone, seeing as Protestants come down on both sides of this question. So, bearing in mind that the church is the pillar and foundation of truth, I’ll prove it by the Catechism, the testimony of the only entity granted authority to speak on these matters:
**1037 God predestines no one to go to hell;620 for this, a willful turning away from God (a mortal sin) is necessary, and persistence in it until the end. In the Eucharistic liturgy and in the daily prayers of her faithful, the Church implores the mercy of God, who does not want “any to perish, but all to come to repentance”:621
**
That should settle it then.
