Josiah was King of Judah-- the southern portion of Israel after its civil war in 931 B.C. Josiah took over in 640 B.C. when he was only eight years old. He was the last good King of Judah during a time when the spiritual life of God's people was seriously declining.
At age 16, Josiah started seeking the Lord. Then at 20 years old, 2 Chronicles 34:3-7 tells us he "began to purge Judah and Jerusalem of its high places, Asherah poles, carved idols and cast images."
Notice all the verbs that follow in 2 Chronicles-- that describe the removal of idols:
Tore down (2x)Do you think Josiah was serious about cleaning house and getting rid of idols?
Cut to pieces (2x)
Broke to pieces
Crushed to powder
How serious are you about getting rid of your idols?
