I was reading the Book of Acts Chapter 2 and the following verses stuck out to me:
"2 And suddenly there came a sound from heaven as of a rushing mighty wind, and it filled all the house where they were sitting.
"3 And there appeared unto them cloven tongues like as of fire, and it sat upon each of them.
"4 And they were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance."
At one point in the book and movie entitled, "Heaven Is for Real" by Lynn Vincent and Todd Burpo, Colton Burpo, the son of a small-town Nebraska pastor (Todd Burpo), described the Holy Spirit as "kind of blue."
Now some people say that statement about the color of the Holy Spirit is unbiblical; but is it really? If you think about the hottest fires having changed in color from red and yellow to blue, then that could make sense with regard to the "cloven tongues" that were "like as of fire." Maybe the color of the fire of the cloven tongues was blue. And maybe, just maybe the Holy Spirit does have a type of blue aurora or something.
Jeremiah 20:9 says, "Then I said, I will not make mention of Him, nor speak any more in His name. But His word was in mine heart as a burning fire shut up in my bones, and I was weary with forbearing, and I could not stay." Jeremiah clearly had his own type of fiery experience in the Old Testament.
If blue is the hottest kind of fire and the hottest is above what would otherwise be yellow and red (metaphorically mediocre), why wouldn't God want to give us the hottest fire to work with? God wants the best for us, so it stands to reason that He'd want us to have the best "fire" experience to draw us even closer to Him.
But hey, that's just my two-cents.
I just want to encourage and inspire as many people as I can for Jesus Christ.
