2 Kings 18 tells the story of the rise of Hezekiah who began his reign at twenty-five years old. The nation had fallen to idolatry, such that even the things of God were used as idols.
Hezekiah was the grandson of Zechariah through his mother, Abi, and did what was righteous in the eyes of the Lord. Though his father's reign was full of idolatry, Hezekiah was devoted to righting the wrongs of his father before him.
When Hezekiah came into power, the people had setup pillars and high places to Asherah, the breasted god. Temples of Asherah were filled with temple prostitutes, sacrificial vessels for blood, and even human sacrifice. While the thought of this is vile and inexcusable, it was not the worst part.
The people had taken the brass serpent that Moses had made for healing, and turned it into an object of worship. Though the serpent on the pole has been considered to be a type of the coming Christ, and was used for God's glory to the people, they placed offerings before it.
Hezekiah placed no value on the earthly things, but worshipped the One True God. Because the people had turned the divine institution of healing that Moses had setup into an idol, Hezekiah destroyed the brazen serpent, breaking it into pieces.
He broke down the pillars and high places of Asherah, and removed all idolatry from his land. Hezekiah wanted his reign to be one filled with power endued from the hand of God, and not of satan.
Because of this, God honored Hezekiah. The Lord was with him wherever he went, and he prospered. He rebelled against the king of Assyria, refusing to serve him. He struck down the Philistines from the far reaches of Gaza and its territory to the watchtower and fortified city.
As Christians, we should ask ourselves: Do we cast out our idols when we learn God's Truth? Have we turned photographs of "spiritual clouds" and "halos" or double-exposed film into idols? If we were asked to get rid of them, would we be superstitious in thinking we would have some great evil befall us for casting our idols out of our house? Have we taken things worse, worshipping a cardboard box of idolatry? Worshipping rotten wood from the "floor of a prophet" to images of belt-buckles and more? Have we setup pillars of Asherah, the breasted god, in our own homes without even knowing it?
