Analyze, learn, contemplate, meditate upon the law of any state, any nation, and you will begin to see the upright heart demanded by its stipulations - though implicative, and at best holding the conscience captive and rectified.
Seek to understand it and you will find a great sense of righteousness through the effect of an understanding of its entirety and inner connectivity.
How much more justice can be seen and sensed in the heart when contemplating Divine Law? Not merely righteousness, but holiness, heaven, and eternal love.
