Someone from the crowd interrupts Jesus, to ask him about how many people will be saved, in the end. Will they be few? many? everyone? only the just? Jesus doesn't answer his question directly. What's important isn't knowing exactly how many will be saved. What's decisive is living with a clear and responsible attitude in order to welcome salvation from that Good God. Jesus reminds them all: 'Try your hardest to enter by the narrow door." In this way Jesus undercuts the reaction of those who understand his message as an invitation to laxity. That makes fun of the Father. Salvation isn't something one receives irresponsibly form a permissive God. It also isn't the privilege of an elect few. It's not enough to be children of Abraham. It isn't sufficient to have know the Messiah, to have heard and seen him. One needs also to follow him, to be known by him.
The invitation to "enter by the narrow door" can be read in light of another saying of Jesus: 'I am the door; the one who enter through me, will be saved." (John 10:9) Entering by the narrow door is "following Jesus"; learning to live as he did; taking up his cross and trusting the Father who has raised him from the dead. In following him, not everything counts, not everything is equal; we need to respond to the Father's love faithfully. What Jesus asks isn't legalistic rigourism, but a radical love for God and neighbour. That's why his call is a source of demand, but not of anxiety. Jesus Christ is a door that is always open. No one can close it, only ourselves if we close ourselves to his forgiveness. (Jose Antonio Pagola)
