What we should be most diligent about, I think, is this. First, we must continually ask God in our prayers to keep us in His hand, and bear constantly in mind that, if He leaves us, we shall at once be down in the depths, as indeed we shall. So we must never have any confidence in ourselves -- that would simply be folly. But most of all we must walk with special care and attention, and watch what progress we make in the virtues, and discover if, in any way, we are either improving or going back, especially in our love for each other and in our desire to be thought least of, and in ordinary things; for if we look to this, and beg the Lord to give us light, we shall at once discern whether we have gained or lost. Do not suppose, then, that when God brings a soul to such a point He lets it go so quickly out of His hand that the devil can recapture it without much labour. His Majesty is so anxious for it not to be lost that He gives it a thousand interior warnings of many kinds, and thus it cannot fail to perceive the danger.
