There is no way to experience tomorrow until it comes.
Time was created for the purpose of human choice - those choices that line up with God's Word! So, because time has intrinsic limitations,we have been clearly instructed not to rehash either the past or the future.
It is one thing to remember the "pit from which you were dug. . " and yet another to imagine a thousand ways the situation could have turned out.
In the same way, it is futile to imagine tomorrow. If I fall into that, I will miss the things that are right under my nose today. What's more, I will essentially lose the time I am spending now, but it is a double loss, because I have not only lost time on fantasy, I have also tainted tomorrow before it comes. I have predisposed myself to ignore the leading of the Lord, and I have set myself up to be my own lord!
He gives sharp clarity for the moment, and when tomorrow's moments come, He will do the same!
