Very interesting question!  While it's tempting to choose talent, my reason for choosing heart is to help heart discover talent.  This is only possible if someone offers heart a chance to show us what she's got!

Jennifer, your post comes at a critical time for me. My 7-year old son plays soccer with heart. While he is the weakest player on his team, he never missed practices or games. In fact one afternoon he fell asleep right before a soccer game! All our efforts to wake him were unsuccessful.  He finally woke up startled, asking what time it was.  At this point the game had already begun. He said, "No, I can't miss the game!  The team needs me!" And so we rushed to the game.

My husband and I have been questioning whether he should continue to play because of his lack of talent.  But perhaps we should let him continue to play because he has heart. And with our parental leadership and support, the talent will come.
