'They have the stuff of saints in them.' At times you hear this said of some people. Apart from the fact that the saints were not made of 'stuff, to have stuff is not sufficient.
A great spirit of obedience to your Director and great readiness to respond to grace are essential. For, if you don't allow God's grace and your Director to do their work, there will never appear the finished sculpture, Christ's image, into which the saintly man is fashioned.
And the 'stuff' of which we were speaking will be no more than a heap of shapeless matter, fit only for the fire..., for a good fire if it was good stuff!
