Earlier in this chapter, Isaiah has been talking about a man cutting down a tree, and using half to build a fire to cook and warm himself…the other portion, carving it into an idol and bowing down to worship. The heart can be deceived, and it can lead us far from, and contrary to God’s Laws. This Spirit of delusion will blind us from the truth, and cause confusion and false belief in our minds. There comes a time, when we can hear and see the truth, but fail to even recognize it. So deluded from what is right and good and Godly, we flounder in lies and deception, unable to even save ourselves. But there is someone much greater, who can open our eyes and ears to the truth, and dispel the deception …”Return to Me,” says the Lord, “for I have redeemed you.”
