I had prayed the sinner's prayer at age 5 and was assured- by others- of my salvation. Yet, I always doubted my salvation and probably prayed the sinner's prayer a hundred more times between ages 5 and 27. Outwardly I may have "looked" like a Christian..I sang in a Christian band, was a camp counselor, went on missions trips, etc. But I was trying to get to God through my works. And it left me burnt out. At 27 I said, "forget it..I'm done with Christianity" and walked away.
Long story shortened- I started going back to church a couple years ago. I got involved in another charismatic church that got swept up in the Todd Bentley revival in Lakeland FL. While searching for youtube videos of the revival, I came across a clip from Way of the Master radio where Todd Friel was explaining what was wrong with that "revival". A suggested video popped up right after that one ended that was Paul Washer's "Shocking Message to 5,000 Youth."
By the end of that sermon, I was fully aware of my wretched state before God, that I had been a false convert for decades and that I was going to hell. I promptly repented and put my trust in Jesus Christ alone. My life has changed since that time, including my world view and religious views. I went from being an Arminian to a Calvinist pretty much overnight. I left that charismatic church and now have more of a reformed viewpoint.
