The Lord often began His statements with the word " Amen" - 'truly', 'certainly', 'surely...I say unto you...'. Yet it was usual to conclude a sentence, prayer or statement with that word (1). But the Lord began His statements with it. And this feature of His style evidently caught the attention of all the Gospel writers. Mark mentions it 13 times, Matthew 9 times, Luke 3 times and John 25 times. And it should stand out to us, too. Jeremias also mentions that " according to idiomatic Jewish usage the word amen is used to affirm, endorse or appropriate the words of another person [whereas] in the words of Jesus it is used to introduce and endorse Jesus' own words...to end one's own prayer with amen was considered a sign of ignorance" . Thus Jesus was introducing a radically new type of speaking. The Lord's extraordinary sense of authority was not laughed off as the ravings of a self-deluded 'holy man'. For the crowds flocked to Him, and even hardened guards sent to arrest Him had to give up on the job for the humanly-flimsy excuse that " never man spake like this man" . And it is that very sense of ultimate authority which amazingly comes through to us today, who have never met Him nor heard His words with our own ears. This is the power of the inspired Gospel records, yet it is also testimony to the extraordinary, compelling power of the Personality which is transmitted through them. The Lord's sense of authority helps explain His mysterious logic in Jn. 8:17,18. The Jews accuse Him of bearing witness of Himself, and that therefore His witness is untrue. The Lord replies that under the Law, two witnesses were required in addition to the accused person. And He argues that He is a witness to Himself, and His Father is too: " I am one that bear witness of myself, and the Father that sent me beareth witness" . But this was exactly their point- He was bearing witness of Himself, and therefore " thy witness is not true" (Jn. 8:13 RV). Yet His reply seems to have silenced them. Clearly the authority attached to Him was so great that effectively His bearing witness of Himself was adequate witness.
