ANSWERING A “HOLY SPIRIT SKEPTIC” ON FACEBOOK

SKEPTIC: I remember thinking that the Holy Spirit is a real thing and fully believing I had felt it before. Now I am an atheist and have no issue saying whatever I want about any god, because there is no reason for me not to say something about a being I have no belief in now.

WESLEY GOSPEL: You never felt it. The presence of God is Someone else standing in front of you. Its not an emotion.

SKEPTIC: Of course I never felt it because it is not real. But I fully thought I had felt it at the time, just as you do now. But then I began to examine it from a rational position, by seeing if I could validate it with evidence, and since I could not, the only rational choice I had was to conclude I had made a mistake. The same as everyone else who claims they have felt God, but can’t provide evidence to prove they have.

WESLEY GOSPEL: The experience that I had happened about 50 times to me from 1999 to 2000. It happened so many times that it couldn’t be mistaken. Atheists and skeptics have worked their wonders on me for years, and yet, those memories were just simply impossible to erase. Either you didn’t experience what I did, or you wanted to be a non-Christian, so you rationalized yourself out of what you experienced. I’d sure hate for that to be me. To know with absolute certainty you had experienced the Spirit of God, and in all honesty, you’re memory and conscience still testifying against you that you’re not being honest with yourself. Something supernatural was there and you can still remember it, but you’ll just distract yourself for the moment. And dwell on other things…or you had an emotional experience: and no signs, dreams, angels, prophets, voices, miracles, or anything else to confirm the experience, or tongues popping out of your mouth without any effort on your part, as the comforting entity that is God’s Spirit surrounded your whole body (Acts 2:4).
