The Olympic Fight of Faith

Olympic glory is for the young. Gymnast Gabby Douglas is just 16 years old, swimmer Katie Ledecky is only 15, and Michael Phelps, age 27, says he's old enough to make these Olympic Games his last.

But the Christian "race" is for young and old. The fight of faith is for the healthiest and sickliest, for the seemingly strong and the weak.

So how is it that an aging Christian — barely able to walk, much less compete in Olympic track and field — can have the wherewithal to run?

John Piper tackles the question here.
