Holiness defined.

     Here is a definition of holiness that I thought was quite good.

     Holiness is a thing of the heart; it is the purging away of the dross of the soul; it is the renewing of our whole nature so that we are made 'partakers of the Divine nature' (2 Pet. i. 4). It makes 'the tree good.'
