Well it seems like it is time to give a little lesson here, one l thought someone would have known, but hey if you did then you could not have poked fun at Christianity.
7 in the scriptures represents completeness, it is connected with perfection it is a running theme throughout the scriptures. So how does this apply to this thread, well the natural rainbow has 7 visible colors this is the perfect bow God set in the sky as a covenant to remind us that there would never be another global flood.
Now the number 6 is a representative of incompleteness and associated with Satan, it is a number of unworthyness. Yep, you've guessed it the gay pride flag only has six of the seven colors and I'm sure l do not have to go into detail about what that means for the LGBT movement do l.
