We have been using this tool for about six months now and I highly recommend it. I did spend extra time adding some additional tags in our Bible. This is a great tool but lacks in the following: leading you to the blessings of your child having a Spirit filled heart, examples of men and women who were Spirit filled and who were disobedient to God. My kids relate and remember stories so I like to not only lead them to a single verse but a story that relates to that heart attitude.
So here are the adjustments or additions we added to ours:
On our tabs I added EX. (examples) and B (blessings) and left plain if it was just a scripture in reference to the sinful nature.
For example, for defiance I tabbed CTB's scripture reference along with others that I pulled from Instructions in Righteousness (doorposts.com) red. I also red tabbed stories that demonstrated defiance and labeled that red tab with an EX.
Then I red tabbed scripture that spoke of a child who was the opposite of the sinful nature of defiance (obedience) and labeled it with a B. Then on that page I highlighted the blessing of obedience with orange.
Here is a picture to show how I label mine.
This page is tabbed red for defiance and I have a EX. and a B.
The orange shows when you obey what God says the blessing will be.
The red is a scripture of disobedience.
I also added sticky notes throughout of rewards and discipline for their heart attitude.
