Jesus said, "Nothing is hidden that will not be shone forth, nor is anything secret that will not be known and become evident" (Luke 8:17 my translation from the Greek).
Through the arts, the the Word of God, although hidden from many, can shine forth and come to be known. The arts can be a testiment to Jesus and a prophetic tool. They are prophetic only at the point the Holy Spirit speaks through them. When the Holy Spirit isn't speaking through them, they can be likened to a blank canvas, a paint brush a pen or an unplayed musical instrument.
Some of the first Christians believed all could prophesy and the Apostle Peter declared that what Joel had prophesied had come to pass.
"I will liberally gush [shed] my Spirit upon all flesh and they will prophesy. Your sons and your daughters, your elders will dream dreams, and youths will see visions. And even on the male servants and on the female servants, in those I days I will gush out my Spirit." (Joel 2:28, My Translation).In saying this, Peter declared the last days had begun, and those who receive the Spirit of God can expect to prophesy. They can expect Jesus to speak to them and through them and not just in words.
For some, prophetic art means end time images of doom and gloom, but Jesus doesn't just speak or shine forth these kind of end time words and images. He shines forth love and solutions to problems as well. He tells the future before it happens, giving those who hear, the opportunity to work with Him to bring about change to the predicted future, or preparedness to meet it (Isaiah 46:10).
