Why markers, signposts, and deltas are important.
Our intellect, will, and strength can take us a certain distance. There is a point, however, when you step outside of those vehicles and must go the rest of the journey fueled only by faith. It is a time for testing our resolve. Another way to imagine it might be to picture a time when you were lost on foot (in the woods) or driving in an unfamiliar region. You are tired, famished, confused, and worried. But then, just then, you see it: a familiar landmark or signpost. Suddenly, you're reinvigorated. Your hope rekindles. It's going to be okay. You're still a good distance from your dwelling, but you now know you're on the correct course and keep your eyes peeled for the next marker to emerge, each bringing you one step closer to safety - to HOME.
