If you nod off and are unable to say "in Jesus name" then the prayer does not make it through. So you could be praying for hours, deep thoughts from the heart and doze off just before the end and all that was in vain.
Which brings up the subject of "Where is the prayer being buffered or recorded up until the point where you launch it by saying the special "In Jesus name"?
Seems like it would have to have been "stored" for lack of a better word by some intermediary of Jehovah until those words are said, since he does not hear it personally until, again, those special words are uttered at the end. Of course once you say those special words, then it is properly forwarded to Jah so that he can hear your prayers.
I think it makes more sense to say those words at the beginning of the prayer, you know, to open the connection before spending all that time praying for nought.
It gives the idea of "In the Cloud storage servers" a whole new meaning, as it were.
