If you love an alcoholic, and he asks you to buy him a drink, will you? If you really care about your friend, you won’t buy that drink, even though you want him to be happy.
If all he’s thinking about is his immediate happiness, he might think you don’t care about him because you won’t give him what he wants.
Man finds it hard to get what he wants, because he does not want the best; God finds it hard to give, because He would give the best, and man will not take it. ~ George MacDonald
