Word is Eternal

Matthew 5:17-18

"Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfil them. I tell you the truth, until heaven and earth disappear, not the smallest letter, not the least stroke of a pen, will by any means disappear from the Law until everything is accomplished."

Luke 21:33

"Heaven and earth will pass away, but my words will never pass away."
