Yes, for the sake of argument, it is Yeshua, who taught not to say Lord have mercy x40.
And he came unto the disciples, and found them asleep, and said unto Peter: "What, could you not watch with me one hour? Watch and pray, that you enter not into temptation: the spirit indeed is willing, but the flesh is weak."
He went away again the second time, and prayed, saying: "O my Father, if this cup may not pass away from me, except I drink it, your will be done."
And he came and found them asleep again: for their eyes were heavy. And he left them, and went away again, and prayed the third time, saying the same words.
Yes, the third time. Trinity anybody?
Let's do a 100 knot prayer rope now.... ?
What did God say?
7 But when ye pray, use not vain repetitions
, as the heathen do: for they think that they shall be heard
for their much speaking. 8 Be not ye therefore like unto them: for your Father knoweth what things ye have need of, before ye ask him.
I've practiced/used the prayer rope as an Orthodox Christian. I've heard the apologetics. I've read about the Jesus prayer. I've been in monasteries witnessing monks use the prayer rope. I absolutely believe it to be repetitious prayer. I disagree with this facet of Eastern Orthodoxy. I know it seems I cherry pick and Orthodoxy seems to come in an "all or nothing" deal.
Nonetheless, it is repetitious, many words, and vain - something GOD commanded us NOT to pray.
I have no beef with the Jesus prayer, I even say it. But I say it once, when I can think of nothing else... In those quick situations when I need a prayer but can't think/busy etc. I believe it is a very powerful and beautiful, yet simple prayer. But I will not disobey God and repeat it over and over.
