John Frye maak hierdie opmerkings:
“What is a spiritual discipline? It is simply a human activity that creates a space or setting for God to work. I do mean for God to work and work mightily. I now understand for example, that solitude and silence are not activities that earn God’s favor or blessing. They are simply practices I choose to do that position me to receive God’s favor or blessing. Since this is true, I would be a fool to be negligent in practicing these two significant, time honored behaviours.” Lees voort “DIE WAARDE VAN STILTE (II)”
