Time as we know it is not eternal, it is created. Before there was time there was God. This is one reason God refers to himself as I Am. God is infinite, he cannot be measured by time. He simply and profoundly is. Time is temporal, having to do with what is temporary. As Paul says, don’t focus on what is temporary, but focus on eternity. Faith has to do with eternity. Worry has to do with time.
Something to think about.
