I was listening to a sermon and heard the word "rapture" and thought that would make a great abstract stained glass panel. After having designed it, I went to Biblos(dot)com and searched for the word "rapture" regarding the second coming of Yeshua. I could't find such a reference to that exact word, and apparently this is a term that "custom" has brought on the subject. I did find a reference which satisfied me, and that is Mark 14:62 where the words of Yeshua allegedly are "I am," said Jesus. "And you will see the Son of Man sitting at the right hand of the Mighty One and coming on the clouds of heaven." (NIV).
This pattern relates to my vision of "coming on the clouds of heaven" with concentric radiations from above intersecting with vertical figures of the raptured souls. BTW, rapture is a great word.
