Let me ask you a question: If I paid you millions of dollars and assembled 80,000 people to cheer for you, do you think you could carry a light piece of leather for a mile? I'll bet you could.
And yet, a strong, skilled athletic football player is rarely able to carry a piece of pigskin one-half mile in an entire football season. A 1,000-yard season makes a football player a superstar; and 1,000 yards is only a little more than a half a mile.
So why are you able to do more than the best football players are not able to do? The reason is the opposition. Why do we have moral failures? Regardless of what you call it - evil, Satan - there is another team on the field.
