It's rational to think god wants us meeting up and singing songs to him. 
Its common sense for  10 ,30, 40 year old single,  married,  familys from around your neighborhood to sing songs together. 
Rash nil. 
I mean rational  
Hold.
Why it couldn't  be NO more then  (Two lines ) into singing songs to the good lord jesus 
Ya rational kicks in .
Thats your rationality.
Or is it. 
We haven't a rationality,   
Thats a different post. 
If atheism is irrational,  theists ,   theism is ummmm,  more irrational. 
And that's just for starters.
