“The promised land always lies on the other side of a wilderness.”
You don’t have to know what the promised land looks like to want to go there. You don’t have to have been there before to make the journey. But, you do have to have the courage to walk through the wilderness, to push forward when it would be easier to turn back, to persevere even when you don’t want to.
No one magically arrives at the promised land; the journey through the wilderness fulfills the promise. Only by making the journey will you know when you get there.
