Worldly people have not the Holy Spirit, or if they have, it is only for a moment . . . The noise of the world drives Him away. A Christian who is led by the Holy Spirit has no difficulty in leaving the goods of this world, to run after those of heaven; he knows the difference between them. The eyes of the world see no further than this life . . . The eyes of the Christian see deep into eternity . . . We must therefore find out by whom we are led. If it is not by the Holy Spirit, we labor in vain.
– St. John Vianney
