I remember watching a TV show as a child where a "prank" was played on an elderly couple that went into a diner to eat. As they at the table they were at "lifted" about half an inch every minute. Before you knew it the table was up to their chest but they just kept on eating because they were not able to recognize the gradual change in the location of the table.
When people fall away from following the Lord they usually will not realize it even when you make the attempt to help them by telling them they have gotten off course. The reason why? It has been gradual. They think they are still the same and yet they are doing things now that they would have never done a year or two ago. Are you one of these people?
