Consider this phrase from Isaiah 44:20: “A deluded heart has led him astray.”

Note that it does not say, “He was deluded about the truth.” Unquestionably that is the case. But the phrase says more: After being deluded about one matter, that very delusion leads us yet further astray from the truth.

In Isaiah 44, this is the case with idol worship. The prophet here mocks the man who takes a block of wood, cuts it up, then uses some pieces to cook food and calls the rest a god. Verse 20 concludes: “He cannot deliver himself or say, “Is there not a lie in my right hand?” Having turned away from the One Who is the First and the Last, the one true God (verse 6), the idol worshiper eventually becomes unable to escape the delusion he willingly chose. He acts foolishly, but can’t recognize it. His chosen delusion leads him further and further from the truth. He is trapped.

This is a great danger that Scripture warns against again and again. Indeed, all fallen humanity is caught in this trap. (more…)
