If you were to fall into the temptation of wondering, ‘who’s telling me to embark on this?’ We would have to reply: ‘Christ himself is telling you, is begging you.’ ‘The harvest is plentiful enough, but the labourers are few. You must ask the Lord to whom the harvest belongs to send labourers out for the harvesting’ . Don’t take the easy way out. Don’t say, ‘I’m no good at this sort of thing; there are others who can do it; it isn’t my line’. No, for this sort of thing, there is no one else: if you could get away with that argument, so could everyone else. Christ’s plea is addressed to each and every Christian. No one can consider himself excused, for whatever reason: age, health or occupation. There are no excuses whatsoever. Either we carry out a fruitful apostolate, or our faith will prove barren.
Besides, who ever said that to speak about Christ and to spread his doctrine, you need to do anything unusual or remarkable? Just live your ordinary life; work at your job, trying to fulfil the duties of your state in life, doing your job, your professional work properly, improving, getting better each day. Be loyal; be understanding with others and demanding on yourself. Be mortified and cheerful. This will be your apostolate. Then, though you won’t see why, because you’re very aware of your own wretchedness, you will find that people come to you. Then you can talk to them, quite simply and naturally — on your way home from work for instance, or in a family gathering, on a bus, walking down the street, anywhere. You will chat about the sort of longings that everyone feels deep down in his soul, even though some people may not want to pay attention to them: they will come to understand them better, when they begin to look for God in earnest.
