Mark 7: 14-15 (14) He summoned the crowd again and said to them, “Hear me, all of you, and understand. (15) Nothing that enters one from outside can defile that person; but the things that come out from within are what defile. [ (16) If any man has ears to hear, let him hear.]”
John 6:60-64 (60) Many of Jesus’ disciples who were listening said, “This saying is hard; who can accept it? (61) Since Jesus knew that his disciples were murmuring about this, he said to them, “Does this shock you? (62) What if you were to see the Son of Man ascending to where he was before? (63) It is the spirit that gives life, while the flesh is of no avail. The words I have spoken to you are Spirit and life. (64) But there are some of you who do not believe.”
John 6:47-51 (47) Amen, amen, I say to you, whoever believes has eternal life. (48) I am the bread of life. (49) Your ancestors ate the manna in the desert, but they died ; (50) this is the bread that comes down from heaven so that one may eat it and not die. (51) I am the living bread that came down from heaven; whoever eats this bread will live forever; and the bread that I will give is my flesh for the life of the world.
