Jesus used His own saliva several times in the Bible to heal. In John 9:6 it says, “Having said this, He spit on the ground, made some mud with the saliva, and put it on the man’s eyes.” In Mark 8:23 it says, “He took the blind man by the hand and led him outside the village. When He had spit on the man’s eyes and put His hands on him, Jesus asked, ‘Do you see anything?’ ” So why did Jesus do this very primal act? We know that Jesus was fully man but also fully God…and within His saliva was His DNA. DNA that held His chromosomes…His genetic information. But the spit Jesus smeared on these men held something much more powerful… it held within it the very essence of God.
