As we delight in and meditate on God and his instructions, we are transformed, nourished, and sustained. The call to action is to set our minds and hearts on the Lord and his instruction, and the result is that we become like trees planted by streams of water. Healthy trees live long lives. They grow deep, complex root systems embedded beneath the ground surface, which helps them weather wind, storms, and droughts. They can bend and sway when the winds come without being ripped from the ground. This beautiful analogy is meant to teach us that though life brings chaos and turmoil our way, we are not uprooted because we have grown deep in the Lord.
