Diamonds are precious and beautiful. They are also the hardest naturally occurring substance. So when Zechariah describes the hearts of the people as like diamonds, it is not a compliment.
“They made their hearts diamond-hard lest they should hear the law and the words that the LORD of hosts had sent by his Spirit through the former prophets. Therefore great anger came from the LORD of hosts.” (Zechariah 7:12 ESV)
A diamond heart is stubborn and resistant. It refuses to hear and to heed the word of God. If your heart is going to be precious in God’s eyes, it must be soft and shaped by His word—like clay in the potter hand.
Submit your heart to God and heed His word today.
