Beware of allowing yourself to think that the shallow concerns of life are not ordained of God; they are as much of God as the profound. It is not your devotion to God that makes you refuse to be shallow, but your wish to impress other people with the fact that you are not shallow, which is a sure sign that you are a spiritual prig. Be careful of the production of contempt in yourself, it always comes along this line, and causes you to go about as a walking rebuke to other people because they are more shallow than you are. Beware of posing as a profound person; God became a Baby.
To be shallow is not a sign of being wicked, nor is shallowness a sign that there are no deeps: the ocean has a shore. The shallow amenities of life, eating and drinking, walking and talking, are all ordained by God. These are the things in which Our Lord lived. He lived in them as the Son of God, and He said that "the disciple is not above his Master."
Our safeguard is in the shallow things. We have to live the surface common-sense life in a common-sense way; when the deeper things come, God gives them to us apart from the shallow concerns. Never show the deeps to anyone but God. We are so abominably serious, so desperately interested in our own characters, that we refuse to behave like Christians in the shallow concerns of life.
Determinedly take no one seriously but God, and the first person you find you have to leave severely alone as being the greatest fraud you have ever known, is yourself.
