"Seeing"
Seeing in the second heaven, the spiritual realm, has become a common experience for me. I liken it to the gifts of tongues, actually the two gifts of tongues. The one gift, the Holy Spirit bursting forth as a result, similar to what is described in the second chapter of Acts of his overpowering presence and influence.
The second gift of when a person simply prays in tongues. My gift of seeing is sometimes be like the second gift of tongues and experienced at will. I simply “look with my spiritual eyes”. It also occurs like the first gift of tongues, when the Holy Spirit wishes to reveal something to me and opens the spiritual world, with no effort of my own, presenting a vision of what He would like me to take notice of.
Since my experience of what is known by the Pentecostals, being baptized in the Holy Spirit, my gift of tongues and my prophetic gift of seeing became much more available to me. It was as if I had been living in a dark black and white world all my life, and someone turned the lights on making everything in vivid technicolor.
However, seeing angels and dark spirits (not always by my choice) and what they were saying or doing can be challenging, and overwhelming at times even though it is quite beneficial.
