“In your apostolic undertakings you are right — it's your duty — to consider what means the world can offer you (2+2=4), but don't forget — ever! — that, fortunately, your calculations must include another term: God+2+2...” (The Way, 471).
You need interior life and doctrinal formation. Be demanding on yourself! As a Christian man or woman, you have to be the salt of the earth and the light of the world, for you are obliged to give good example with holy shamelessness.
Christ expects a lot from your work. But you will have to look for souls, as the Good Shepherd went after the hundredth sheep: without waiting to be called. Then make use of your friends to do good to others. Tell each one of them that nobody can feel at ease with a spiritual life which, after filling him, does not overflow with apostolic zeal. (Furrow 223)
You run the great risk of being satisfied with living, or thinking that you have to live, "like a good boy", who stays in a cosy and neat house, with no problems, and knowing only happiness. That is a caricature of the home in Nazareth. Because Christ brought happiness and order, he went out to spread those treasures among men and women of all times. (Furrow, 952)
The harvest is great and the laborers few. Rogate ergo! Pray therefore the Lord of the harvest to send out laborers into his harvest. Prayer is the most effective means of winning new apostles. (The Way, 800)
'Duc in altum. Put out into deep water!' Throw aside the pessimism that makes a coward of you. And pay out your nets for a catch! Don't you see that you, like Peter, can say: 'In nomine tuo, laxabo rete': Jesus, if you say so, I will search for souls? (The Way, 792)
If your prayers, your sacrifices and your actions do not show a constant concern for the apostolate, it is a sure sign that you are not happy, and that you have to be more faithful. The man who possesses happiness, and the good, will always seek to give it to others. (The Forge, 914)
You will not lack the grace of God. Therefore, if you respond to it, you will be sure to win. Victory depends on you: your strength and drive -- together with that grace -- are reason enough for you to have the optimism of one who knows victory is assured. (Furrow, 80)
Be convinced of this: your apostolate consists in spreading goodness, light, enthusiasm, generosity, a spirit of sacrifice, constancy in work, deep study, complete self-surrender, being up-to-date, cheerful and complete obedience to the Church, and perfect charity. Nobody can give what he does not have. (Furrow, 927)
Don't let your life be barren. Be useful. Make yourself felt. Shine forth with the torch of your faith and your love. With your apostolic life, wipe out the trail of filth and slime left by the corrupt sowers of hatred. And set aflame all the ways of the earth with the fire of Christ that you bear in your heart. (The Way, 1)
You are to be yeast within the great multitudes that make up humanity remember we are interested in all souls. In this way, with God's grace and your own correspondence to it, you will act as leaven throughout the world, adding quality, flavour and volume to the bread of Christ so that it can nourish the souls of others. (The Forge, 973)
Don't be narrow-minded men or women who are immature, short-sighted and incapable of embracing our supernatural Christian outlook as children of God. God and daring! (Furrow, 96)
