"Many a man, brought up in the glib profession of some shallow form of Christianity, who comes through reading Astronomy to realize for the first time how majestically indifferent most reality is to man, and who perhaps abandons his religion on that account, may at that moment be having his first genuinely religious experience."

The first step to be taken by one who wishes to follow Christ is, according to Our Lord’s own words, that of renouncing himself - that is, his own senses, his own passions, his own will, his own judgement, and all the movements of nature, making to God a sacrifice of all these things, and of all their acts, which are surely sacrifices very acceptable to the Lord. And we must never grow weary of this; for if anyone having, so to speak, one foot already in Heaven, should abandon this exercise, when the time should come for him to put the other there, he would run much risk of being lost.
