Two verses that show yet again that there is an inability on the part of unsaved man. Jesus is dialoging with the Pharisees who reject his message. They are arguing that Christ was an illegitimate child (v. 41) and that their father was God. Jesus corrects them by saying that if their father was God, they would love him because he came from God. He then says, "Why do you not understand what I am saying? It is because you cannot hear My word. "You are of your father the devil, and you want to do the desires of your father. He was a murderer from the beginning, and does not stand in the truth because there is no truth in him. Whenever he speaks a lie, he speaks from his own nature, for he is a liar and the father of lies.'" Notice the last phrase of v. 43: You cannot hear my word. IT should be immediately apparent that ability was at issue since the word is "cannot" as opposed to "will not." It should readily be apparent that "hearing" is not simply audible reception, since the fact of the conversation meant that their physical hearing worked fine. It should also readily be apparent that the next verse gives the reason why they could not understand: They were of their father the devil. These people could hear, but they could not "hear," i.e., with understanding. Once again we see Christ address the issue of ability. In so doing, he makes it clear that inability is the inherent nature of children of the devil. At some point, we should stop having the discussions about whether inability is a part of sinful nature. Christ himself said it was. Why argue about any further?
