Commentaries:
"Written in the earth" - written in dust. What happens to anything written in the dust? The wind comes along, and it blows away. Those who do not trust God, who depart from the Lord, who allow their heart to deceive them into not properly responding to the truth of God—their names are just going to blow away like something written in the dust.
Do we really believe Him enough to live by faith? The person who lives by faith is one who believes God's truth and responds in obedience to it. The person who does not departs from His truth.
