It is not true that Jesus did not write as noted here. He wrote, created, and redeemed the world with one word written in the dust. So it is that we in faith use technology and by means of that same sand in the form of computer chips (the gift to Zebulun) make images and words do his bidding.
While Jesus needed no technique, we learn through his Anointing the power of word and image that we too might be one. If indeed like him, we empty our words of self, they also will do his will. In this action we become as he is, miracle livestock.
