The apostles were very sure that everything of theirs which had to do with salvation was a gift to them from God. 'Increase our faith'. They did not presume that the fullness of faith would come to them merely because they freely opted for it. They believed, rather, that it was a gift of God which would have to be granted to them.

... when death has been brought upon a saint, we ought not to think that an evil has happened to him but a thing indifferent; which is an evil to a wicked man, while to the good it is rest and freedom from evils. 'For death is rest to a man whose way is hidden' (Job 3:23 LXX). And so a good man does not suffer any loss from it.

If you want to correct your brother when he is doing wrong? you must keep yourself calm; otherwise you yourself may catch the sickness you are seeking to cure and you may find that the words of the Gospel now apply to you? 'Why do you look at the speck of dust in your brother's eye, and not notice the rafter in your own eye?'
