A plumb line was always an important builder’s tool. It is simply a piece of string with a weight attached to one end. When you hold the loose end up at the top of a wall, the string hangs perfectly vertical. One can tell accurately if the wall is straight or not. The Lord used that image through the prophet Amos. “Look, I am setting a plumb line among my people Israel…”(7:8) God was judging Israel by His exact standards. In our modern day, we would say that plumb lines are fine for building, but don’t apply them to us. We don’t believe there are any exact standards today. Everything is relative. A standard that is right for you is not always right for me. But that is like saying, gravity (which make the plumb line work) doesn’t really apply everywhere on earth. We have just celebrated the Good Friday/Easter event declaring God’s saving grace, and our freedom from sin and death. That is our wonderful Gospel proclamation, but that, in no way, negates the standards God has provided for our life with Him.
