Hi Brother, of course none of us have ever seen Gods Throne or could ever imagine with our feeble earthly minds what It may or may not look like, or indeed what that Lord in all his Glory will look like. However I used the rainbow effect around Gods Throne from
Ezekiel 1:28 As the appearance of the bow that is in the cloud in the day of rain, so was the appearance of the brightness round about. This was the appearance of the likeness of the glory of the LORD. And when I saw it, I fell upon my face, and I heard a voice of one that spake.
As for the lightnings
Revelation 4:5 And out of the throne proceeded lightnings and thunderings and voices: and there were seven lamps of fire burning before the throne, which are the seven Spirits of God.
God Bless
PS. Anyone that does wish to have them printed out for posters, please ask for higher resolution copies from my original files for printing.
However anyone wishing to print them on A4 in tiles to put together from their own computer may use a net based program like this to create the necessary files for printing.
