The tenth commandment forbids coveting. It is aimed at our hearts and God alone sees the heart. Pastor Paul van Engelenhoven uses Psalm 139 to show covetousness exposed before the eyes of God and covetousness defeated through the love of God.
“Search me, O God, and know my heart! Try me and know my thoughts! And see if there be any grievous way in me, and lead me in the way everlasting!”
