The purpose of roots is to get water. But these roots are taking up all the ground which is allotted to this Honey locust tree which isn't much. I've seen many trees planted in sidewalks die. I'm assuming the roots of this tree must have tapped into some sewer line or other source. How could the tree survive otherwise?
Just as this tree has a limited water source, it found a way to survive. Christians need to find a source of nourishment also to thrive in their walk with the Lord. Don't neglect your source of nourishment from the Bible. Your spiritual life depends on it. Let the Lord guide you to green valleys.
"The meadows are clothed with flocks and the valleys are covered with grain; they shout for joy, yes, they sing."
