I will live in the past, the present, and the future! (Charles Dickens, 19th century English writer)
We often hear that we can’t live in the past or future, so we must concentrate on the here and now. However, Dickens may have a point. Our past certainly has affected us in both positive and negative ways. We must learn those lessons. And, of course, as we live today, we have to be planning and preparing for the future. So, yes, we do live in a three-dimensional time frame.
For everything there is a season, a time for every activity under heaven (Ecclesiastes 3:1).
