A man who walked from New York City to San Francisco was asked what his biggest hurdle was. He said that the toughest part of the trip wasn’t traversing the steep slopes of the mountains or crossing hot, barren stretches of desert. He said, “The thing that came the closest to defeating me was the sand in my shoes.”
It is not usually what we think of as big sins that defeat us. Most Christians fall to sins that they do not think are very big.
