Don’t talk to him any further about drinking.
Instead, on suitable occasions, talk to him about God. Tell him what He is and
what He means to us. If he is able to understand that, he’ll ask you how he
should stop drinking. But even here, don’t pester him. Your attitude towards him
should be the attitude of a person who sees his friend moving towards his own
destruction. Therefore, your attitude towards him should be of love and concern.
To make yourself effective in this regard, you’ll have to maintain your ethical
superiority at all times in mutual dealings.
