You cannot step into the same river twice. (Heraclitus, 6th century B.C. Greek philosopher)

What do you suppose Heraclitus meant? If you step into the Mississippi at Dubuque, Iowa, are you in a different river from the water you might step into in New Orleans? Or if you dip in at the same place but at a different time, is it the same river? Perhaps the philosopher is merely reminding us that nothing is ever the same even a moment later; change is constant.

But “Jesus Christ is the same yesterday and today and forever” (Hebrews 13:8).
