cross over

Attention, Israel! This very day you are crossing the Jordan to enter the land...
Deuteronomy 9:1a

There is a time to cross over, a window of opportunity so to speak. Timing is everything.
If there's a time to go, a time to strike, a time to act; what do you do before that window comes? Prepare. Be prepared. Get ready.

Here's a key point about transition that is simple, yet profound: You have to fully leave in order to fully arrive. If you don't fully leave, then you can not fully arrive, at your new destination, because part of you is still "back there" or you've brought some of the "back there" to the "here". What's sad and what you don't want is to be in a new place with your old stuff. Grieve the loss and be healed.
