Calvin on John 6:2, where the multitude follows Jesus away from town:

Here we see, in the first place, how eager was the desire of the people to hear Christ, since all of them, forgetting themselves, take no concern about spending the night in a desert place. So much the less excusable is our indifference, or rather our sloth, when we are so far from preferring the heavenly doctrine to the gnawings of hunger, that the slightest interruptions immediately lead us away from meditation on the heavenly life. Very rarely does it happen that Christ finds us free and disengaged from the entanglements of the world. So far is every one of us from being ready to follow him to a desert mountain, that scarcely one in ten can endure to receive him, when he presents himself at home in the midst of comforts. And though this disease prevails nearly throughout the whole world, yet it is certain that no man will be fit for the kingdom of God until, laying aside such delicacy, he learn to desire the food of the soul so earnestly that his belly shall not hinder him.
