Even if rocks are erected on top of dirt, if the ground is even, then the rocks will never fall. However, rocks that are erected on top of an angle will never be able to stand because the dirt will eventually slip and slide.
I am always in the process of getting ready and preparing before I do anything. Whenever I place a boulder, I ask God whether He likes the way the boulder has been placed. Since God is always watching, I can work with perfection. I push myself to do my best whenever I place a boulder. It’s to the point where I can’t do any better. If someone asked me to take the boulders out and reposition them, I wouldn’t be able to place them any better.
