I was reminded this week of just how much things change when I assumed something was just like it was thirty years ago! How silly and irresponsible of me! The Greek philosopher Heraclitus said, “You can’t step into the same river twice.” There is a continual current of change happening all around us. We need to stay abreast of those changes and understand them. At the same time there has to be solid foundation in our lives that never changes. Hebrews 13:8 says, “Jesus Christ is the same yesterday, today, and tomorrow.” That’s the solid rock.
