In St. Louis there is a railroad switchyard. One particular switch begins with just the thinnest piece of steel to direct a train away from one track to another. If you were to follow those two tracks, however, you would find that one ends in San Francisco, the other in New York. Sin is like that. Just a small switch, a choice this way or that, will cause us to deviate from God’s will, placing us far afield from our intended destination.
