This limitation of creative endeavor is supposedly for their good, to insure that they remain on the narrow way and get not deceived, defiled and led astray by unbelievers of every stripe, as well as Satan and his minions. It is good for nothing anymore, except to be thrown out and trampled under foot by men. You are the light of the world. A city set on a hill cannot be hidden. We are all to be salt and light in our sphere of influence.
Salt includes compassion and humility.
Light encompasses discernment and liberty. We are to manifest these attributes so our unbelieving fellow artists, patrons and arts perceivers might see the Father, through our lives and our good works, and be transformed to ultimately give Him glory. This is why we need to be in the furnace of the artistic marketplace, in our communities and in our nations. We should also, of course, be of some availability to the Church. We must overcome in our own personal spheres of creative influence and in the situations encountered daily in the one and only world.
