Keep company with an unsaved man, and it is more probable you will, in the end, become like him. That is the general consequence of all such friendships. The good go down to the bad, and the bad do not come up to the good. The world’s proverb is only too correct: “Clothes and company tell true tales about character.” “Show me who a man lives with and I will show you what he is.” . . . But depend on it, bad company in this life is the sure way to procure worse company in the life to come.
