Your ordinary professional work will provide the true, solid, noble material out of which you will build a truly Christian life. You will use your work to make fruitful the grace which comes to us from Christ.
Faith, hope and charity will come into play in your professional work done for God. The incidents, the problems, the friendships which your work brings with it, will give you food for prayer. The effort to improve your own daily occupation will give you the chance to experience the cross which is essential for a Christian. When you feel your weakness, the failures which arise even in human undertakings, you will gain in objectivity, in humility and in understanding for others. Successes and joys will prompt you to thanksgiving and to realize that you do not live for yourself, but for the service of others and of God.
If we want to live this way, sanctifying our profession or job, we really must work well, with human and supernatural intensity… The “miracle” which God asks of you is to persevere in your Christian and divine vocation, sanctifying each day’s work: the miracle of turning the prose of each day into heroic verse by the love which you put into your ordinary work. God waits for you there. He expects you to be a responsible person, with the zeal of an apostle and the competence of a good worker. (Christ is passing by, 49-50)
