 Don't lose sight. When you get down into verse 24 through 27, you see the engagement of other senses. He says, be careful the things that you say. Be careful where your feet go. You see the charge to use our whole being, the engagement of all of our senses, to try to protect, to guard our heart. So I was reading this. I was struck by a song that they used to sing in the preschool at church that I grew up in.
