Jehovah is the father of tender mercies, with whom their no variation or turning of a shadow. Needless to say that since Jehovah is a spirit he does not digest food and has no need of a large and small intestine which is the main cause of such physical disturbances. So that one would be correct in assuming that these obnoxious sounds and smells do not exist in heaven, none of God's angels fart except maybe Satan and His Demons being that they have the power to materialize in human form(pre-flood days when Noah lived, and they were all farting up a storm before the flood came). No doubt when they went back up into heaven they let a few rip just to be mean to their fellow angels who also could materialize noses and ears to find out what a fart sounds and smells like. Hey if Satan is the ringleader of all these stars that were cast to the earth with his big tail when Satan was a Dragon you can be sure that if farting make Jehovah sad he will do it just for the thrill of getting Him all sad and whatnot.
As we can see while Jehovah is always the Happy God, with only momentary lapses into sadness caused by farting at wrong times for the practice. Since Jehovah doesn't wear a mood rings we need to look closer at what the bible say about things obscene and try to imagine how Jehovah feels about flatulence
The Bible shows us that Jehovah has lots of emotions, like hate, jealousy,love,regrets,angry, and the like and sometimes he has emotional build ups to the point that he wants to kill every living thing on the planet that breaths(flood of Noah's day and excelent example). As to Jehovah getting upset we see that priest were not wearing the proper type of under garments can really set him off(see Ezekiel 44:17-19 no sweaty balls allow in his temple, it makes God sad).
Since Jehovah had his Son die for our sins will Jehovah find fault with our farting durring prayer? The answer to that question depends on whether or not the fart was done intentionally during the prayer with proper remorse or if it was caused by a monentary loss of control over the spincter muscle in the anus, in the latter case all is forgiven but for the deliberate profaners of Jehovah's prayers all we can say is: "it is a fearful thing to fall into the hands of a sad as well as angry God Jehovah, so one would really need to think twice about whether or not to let it rip durring prayer.
mmmm
