I was raised in a pentecostal, holy roller, charismatic church that was later branded a cult. It was legalism to the extreme and I hated it. I rebelled against the church, the beliefs, my parents, and foolishly blamed God for everything that man had done. I spent the better part of my young adult life as an agnostic. I was always interested in theology and religon, but I hated denominations and legalism with an undying passion (still do to a certain degree). I still read the Bible at times, but it was from a far different vantage point. Even here on AR15.com, I spent time decrying Christianity, proclaiming my agnosticism and rational skepticism to the whole world.
This past year, a lot of past events started coming full circle in our lives. Events that happened in the past, people that I had met, and other connections that were far too outlandish to explain away the odds as circumstance. Then a series of events started happening that culminated in a direct experience with the Holy Spirit that my wife and I both shared at the same time (which pretty much leaves out the possibility of mental illness or hallucinations...). I had no choice but to accept the fact that as much as I thought I had a handle on the physical world around me, I knew absolutely nothing. I am a data/software analyst by trade. I live and breathe logic in a world of black and white, binary 1's & 0's. I had no explanation for the things that were taking place around me, and I had no way to calculate the odds of the events and connections.
After talking extensively with my wife one evening, she asked me how all of these things could be happening and if this was real. I finally proclaimed, "Because it's GOD, that's why... there's no other explanation." Maybe someday I will share the events of that evening, but I have always refrained because I'd rather not put things in front of people which sound fantastic and crazy. I'd rather simply allow my testimony to be reflected by the pronounced changes that have taken place in my life. During that experience though, my wife and I both accepted God, prayed and asked for forgiveness, and have since walked with Him on a daily basis. Our experiences have been further confirmed by answers to prayers that we pray, and the undoubtable ongoing presence of the Holy Spirit in our daily lives.
You can never blame God for the disgusting things that men do to each other. Even if we don't believe in Him, He's still there and He still loves us. Being a Christian is extremely difficult because it is ultimately so simple in concept. Man has taken that which was simple, and turned it onto all sorts of complex, ritual-laden games.
Seeking to develop a relationship with God on a one-on-one basis through earnest prayer and obedient willingness to follow His Will is pretty much all that it takes -- despite what the local denomination will preach to you.
