Psalm 106:20 “They exchanged their glorious God for an image of a bull, which eats grass.”
God’s people, the Children of Israel, worshipped metal in the form of an animal.  The image had zero spiritual value, yet people worshipped it.  They could not be more foolishly empty.  I have a pen and pencil in front of me.  Those writing instruments can make interesting lines on paper.  Should I worship them?  Why not?  How foolish can one be?  The True, Glorious God, our Redeemer is right before our eyes.  There is but one magnificent God.  Enjoy and worship Him with all your heart, soul and mind.
