On that day – this is the declaration of the Lord of Hosts – “I will erase the names of the idols from the land, and they will no longer be remembered. I will remove the prophets and the unclean spirit from the land.” Zechariah 13:2 HCSB
When I take my shirts to the cleaners I always request that they treat the collars and the cuffs. That is where my shirts seem to get the dirtiest. The cleaners will then add a little extra cleaning power to those areas of my shirts to make sure they are clean. At times I will have a spot on my shirt where I spilled something while eating. Again, I call attention to that spot and ask the cleaners to treat it. They usually want to know what the stain is, so they can properly remove it.
This verse is a description of the end times when God will establish His kingdom. All evil and false gods will be removed. In the end times there will be false prophets who will spread an unclean spirit throughout the land, but God will someday cleanse the world of every false prophet and every unclean spirit.
Challenge: Pray that God will come quickly to remove all sin and to establish His new heaven and new earth. Ask Him to cleanse your heart of any idols or false gods. Pray that God will cleanse you of all evil and give you a heart for those who are unbelievers.
