“For the flesh lusteth against the Spirit, and the Spirit against the flesh” (Galatians 5.17 KJV)
Jesus recognized that there are those who hear, and those who really hear. I enjoy the way Eugene Peterson paraphrases Isaiah 6.9 in verse 10: “Their eyes are open, but they can’t see a thing. Their ears are open but they can’t hear a thing.” Do you know anyone like that? Do they live in your house? Do they wear your pajamas?
