Psalm 1 gives us great picture contrasts of a life lived for God versus a life lived in wicked opposition to Him. The one who follows God, obeys Him, and delights in His Word is "like a tree, planted by streams of water . . ." Trees grow deep roots and taller and stronger as wind buffets them. Through storms, however, that root system keeps them in place. They do not move from where they are rooted. If we are rooted in our God and His Word, we will not move or be shaken, either.
