I will tear down the wall you have covered with whitewash and will level it to the ground so that its foundation will be laid bare. When it falls, you will be destroyed in it; and you will know that I am the Lord. ~ Ezekiel 13:14
This passage refers to the false teachings of false prophets. God promised those who were misleading the children of Israel they would be severely punished. How many churches, some with thousands of congregants, are teaching anti-Biblical doctrine today? How many preachers are perverting, or outright contradicting, the word of God? How many are being misled, and therefore disappointing the One True God?
Would God not punish these contemporary false prophets like He did those of Israel?
Folks, get out your Bibles. Make sure the preacher you're following, the church you're attending, is following the Sovereign Lord. God didn't change. God doesn't change. God is the same as He was when Ezekiel prophesied the destruction of Israel's false prophets.
The only way to know if your preacher is teaching the Bible is to get it out, read it, and study it!
