i've said this already, but i'll re-iterate:
i can recreate any of the pictures you've posted. they are dust or water droplets & nothing more. don't be deceived. NONE of the pictures in this thread are pictures of spirits. i posted that picture i took just to demonstrate how easy it is to get that kind of image. after it gets dark tonight, i could make 100 more, if i thought it was worth doing.
i've read every testimony in the link and not one of them mentions Christ. the true Holy Spirit testifies of Christ.
i do not doubt that there is a spiritual world or that some subset of the testimonies in that link represent actual spiritual encounters. BUT if it was the Holy Spirit that they encountered, they would have been moved to glorify Jesus - and not one of them did.
therefor if any of those encounters with the supernatural are real and not deception, it was another spirit, not the Spirit of God. you need to be careful. demons are very real, and Satan himself is an angel of light.
i'm not saying this as if i have never encountered the supernatural myself, friend. i'm just telling you: 99 out of 100 'spirits' that manifest themselves to men are not what they make themselves to appear to be.
