We learn, from this passage, how ready Christians are to be puffed up with success. It is written, that the seventy returned from their first mission with joy, “saying, Lord, even the devils are subject unto us through thy name.” There was much false fire in that joy. There was evidently self-satisfaction in that report of achievements. The whole tenor of the passage leads us to this conclusion. The remarkable expression which our Lord uses about Satan’s fall from heaven, was most probably meant to be a caution. He read the hearts of the young and inexperienced soldiers before Him. He saw how much they were lifted up by their first victory. He wisely checks them in their undue exultation. He warns there against pride.
