Under the right conditions and the guidance of a master, over a period of time grape juice can be transformed into a fine wine. However, there is no natural process that will ever instantly change water to wine. That requires the touch of a different Master.
The same is true of fallen, sinful, broken and damaged people like you and me. We long for transformation. We wish for it, we work for it, we even pay for it. But all it truly takes is the touch of the Master.
