In Psalm 1, we see the contrast between good & evil. There are two options for us and ultimately it is a choice – our choice. Will we delight in the law (words) of the Lord or will we rely on our own wisdom?
We have the option of the stability offered to us and described as a strong tree that is nourished by the riverbank or we have the option of self-reliance that offers no stability because as an individual my choices can lead to destruction. Much like chaff in the wind, my mind can change and shift like the sand when the ocean waves hit the shore.
Having a sure foundation is the only way to weather the storm. When do my leaves wither? When am I blown around in the wind? — when I am not spending time drinking in the Word of the Lord.
