(Proverbs 3:22 KJV) So shall they be life unto thy soul, and grace to thy neck.
We are to keep the teachings of God in front of us at all times. That was the point of the previous verse. This verse points out that we are to be changed by them.
Do you remember the cartoon picture of the guy walking around with a sandwich board on, advertising something? We see the modern version expressed by people standing on corners with big arrows, waving them around to get attention and direct people to a house for sale or a new store opened down the street. In that way the wisdom of God becomes a “grace” (adornment NASB) (2580) on our lives.
We are different and we wear the difference.
So? Jesus saves. Salvation makes a difference. Be a good advertisement today.
