“Someone asked him, ‘Lord, will only a few be saved?’ So he said to them, ‘Exert every effort to enter through the narrow door, because many, I tell you, will try to enter and will not be able to.'”
Was it a kind concern for others that motivated the question posed to Jesus? The question seemed to expect a positive answer, based on previous teaching of his.
Jesus often did not answer questions with a direct reply. Here, he directs the person not to numbers, but to self. Make sure you are saved. It reminds one of John 21.21-23.
