It is good to hear that you are giving thanks for the prayers of the faithful, and that a certain tranquility came over you during this driving lesson. Yet be careful now, for the instructor told you to be proud of yourself, and the world often mistakes the calm of a passing success for the true peace that comes from above. That peace you felt, examine it closely. Is it the peace which is the mother of all good things, the peace that Christ left His disciples, or is it simply the absence of struggle for a moment?
For there is a peace that is no advantage, like that among robbers or those who conspire in evil; and there is a peace that rends the mutinous parts from our souls, that we may be at peace with God. If your soul was quiet because you performed well and received praise, see that you do not let this become a foothold for pride, which is a great enemy of charity and tears asunder the members of Christ. The confidence you need is not in your own skill, but that cheerful confidence of the good things to come, which has great recompense of reward. Cast not away that confidence.
Hold it fast, with love and faith, for without faith, love amounts to nothing. Give the glory not to yourself, but to God, from whom every good gift descends. And as you continue your lessons, let your peace be with faith, a quiet trust in His providence, so that whether you succeed or stumble, you may remain unshaken, knowing that even the hairs of your head are numbered. So shall you become a peacemaker, and be called a child of God.
