Well, the most prominent spiritual experience in my recent memory was about 7 years ago.
To keep a very long and painful story as short as possible, I was deeply in love with my (now ex-) girlfriend, but she left me for someone else. I'd done and said many things which I now know I shouldn't have, and this rejection threw me into a suicidal fit. My heart felt so consumed by loneliness, pain, and anger, and I wanted to just end everything. So, crying my eyes out, I grabbed a large kitchen knife, intending to slit my wrist. I din't want to die, but I figured life had nothing left for me at that point. My entire world was wrapped around my love for this woman, and now it was gone.
The blade had just touched my arm when I heard an audible, gentle voice: "Put it down." No one else was there, so I thought I was imagining things. Again, the voice said, "Put it down." Tears filling my eyes, I simply asked, "Why? I've got nothing left! I don't belong here!" One more time, the voice simply said, "Put it down." I knew the only explanation for it was God, so I again asked, "Why?"
Suddenly, I experienced what I could only describe as a vision from God. I saw my gravestone, leaves blowing around all over the place...and the woman I loved, crying her eyes out. The only thing she kept saying was, "Why? Why'd you do it? Was it because of me?" I realized that God was showing me what would happen if I went through with suicide. Still in deep emotional pain, I knew that putting my ex or anyone I loved through the same feelings would be even worse. Resigned, I dropped the knife...and to this day, I've never attempted suicide again. That doesn't mean I haven't thought about it, but I've made my choice: it's life.
