What does it mean to be planted like a tree in Psalm 1?

In Psalm 1, the imagery of being like a tree planted by streams of water encapsulates the essence of spiritual stability and growth. This metaphor indicates that those who delight in God's law are provided with everything necessary for spiritual vitality. Just as a tree receives nourishment from water, believers draw sustenance from God's Word, enabling them to bear fruit in their lives. This imagery conveys that blessing involves not only the fruits of obedience but also the deep-rooted foundation provided by God Himself, ensuring that their lives flourish even amidst trials.
