The subtlest of snares

'How fantastic!' said I.

'Do ye think so?' said the Teacher with a piercing glance. 'It is nearer to such as you than ye think. There have been men before now who got so interested in proving the existence of God that they came to care nothing about God Himself . . . as if the good Lord had nothing to do but exist! There have been some who were so occupied in spreading Christianity that they never gave a thought to Christ. Man! Ye see it in smaller matters. Did ye never know a lover of books that with all his first editions and signed copies had lost the power to read them? Or an organiser of charities that had lost all love for the poor? It is the subtlest of all the snares.'
