In one of my all time favourite talks, Tim Saleska tells the story of his room-mate at college. His room-mate was engaged, but his fiancée broke up from him leaving him totally devastated.
The room-mate tried everything he could to win the girl he loved back. He probably gave her space, bombarded her with love letters, sent gifts, drove across the country to tell her all he felt for her, guilt-tripped her, even threatened. Nothing worked.
As Tim Saleska said, you cannot do anything to make someone love. It's something beyond the control of Aladdin's Genie and it's certainly beyond me. I cannot even make myself love something. There's a reason its called "falling in love" and why we talk about being "captivated"... its something beyond our control.
So, we cannot persuade our friends, family, colleagues and strangers to love Christ. We cannot threaten them enough with the consequences of not loving him, or present him as so attractive that he is irresistible. Their hearts are not won to Christ. The Father sets his love upon them and through the Word and by his Spirit gives them a heart transplant - killing the old heart and giving them a new one that beats for him.
