Firstly, I spent the first 12 years of my Christian life in Pentecostal churches. Then I left that movement for a number of reasons. I think it was after I discovered English Puritan authors, and discovered that most Pentecostal preachers tend to bang on one string rather than use the whole orchestra. Also, in my last Charismatic church (mixture of Baptist and Open Brethren plus a few Presbyterians and Pentecostals) was either having one foot in the world, or very legalistic, and having a self-appointed "senior elder" who was very controlling when some unfortunate victims experienced spiritual abuse. I became very disillusioned with the whole thing and decided to part ways. I spent a couple years with an Anglican church, then around eight years in Baptist churches in Christchurch and Dunedin, and then settled into 23 years as an elder of the Presbyterian church. But I never became a cessationist though.
So my ID as a "Pentecostal" on the forum is the only one I could find that enabled me to post and debate in the appropriate "spirit filled" and "spiritual gifts" forums.
While as a Pentecostal I was somewhere between Arminian and Calvinist. I read the first 400 page volume of Arminius' works and found that although he opposed Pelagius, he didn't agree with Calvin either. Actually, he was much more tolerant than Calvin with dissenters, and is reputed to live a more holy life. I think that Arminius was the victim of bad press from the dominant Calvinists of his time.
Read the Puritan authors gave me a much stronger foundation than the Pentecostals, and in recent years have gained many pearls of wisdom from Calvin's Bible commentaries. So, you could call me a Calvinist Continuist if I need a label.
Concerning the prospect of genuine converts losing their salvation, my answer is that if a person is truly converted to Christ, and has Christ revealed to him by the Holy Spirit, and has resulting on-going fellowship with Him on a personal level, why should he want to walk away from Christ? If the person has truly been converted and transformed so that walking with Christ has become his new nature, I can't see that his new nature would allow him to reject Christ and lose his salvation. Walking with Christ is much more than having fire insurance policy to keep out of hell, and a ticket to get into heaven.
I tried to be a good Christian for the first two years of my Christian life, but I knew that although I did everything expected of me on the religious level, there was something missing. I didn't know God on a personal level. I came to the point where I thought, "What is the point of all this religious stuff if I don't know the God behind it all?" So, I sought God with all my heart to get to the place where I could actually meet Him personally. It all came to a head when I got out in the middle of a park on a starry night, looked up and said, "I know that you are in earshot of my voice, and I am telling you that unless I meet you personally, I'm going to throw all this religious stuff way and go back into the world to enjoy my life." Then I said, "I have come to introduce myself to you. You are God and I am me, and I'm very glad to meet you!"
I can't tell you how it happened, but one moment I didn't know the Lord, and the next I did. I felt all lit up inside and heard a distinct voice in my mind, like my own thoughts but somehow different. He said, "We have been waiting for you to put aside the religious stuff and come directly to us." He then said, "Walk before Me and be perfect." After that He said, "This is life eternal that you know the only true God and His Son Jesus Christ." I didn't know where those verse were in the Bible, and went and looked them up later on. After that I decided that now I was in personal contact with the Lord, I decided to ask Him all the questions I had. He answered them all right from the Bible with verses I didn't know where in the Bible and I had to look those up later.
When I got back among my Christian friends, they said, "You are different. What happened to you?" I knew what had happened. I met the Lord personally. That was April 1969, nearly 52 years ago. I believe that was when I was genuinely converted to Christ. It was a total transformation of my heart and attitude toward the Lord. The Bible became a new and living book to me. Prayer became different. Instead of trying to be religious in my prayers, I could speak to Him like He is my best friend. Some of my best times of prayer was walking along a long, isolated beach, with my hands in my pockets, chatting with the Lord about anything that came to mind. When I discussed Scripture with Him, fresh thoughts and insights came to mind that caused me to know that God was speaking back to me, teaching me sound doctrine.
After entering into a relationship with the Lord like that, it has and is unthinkable for me to desert my Saviour who made Himself real to me and showed me that He enjoys having fellowship with me. He gave me the Scripture, "Truly our fellowship is with the Father and His Son Jesus Christ." That is fellowship like no other. It is part of my nature and so much a part of my life that there is no way that I would depart from Him at any time. One day I will meet Him, and get a pleasant surprise to recognise Him as the Person I have walked with and fellowshiped with all my life.
So, I believe that a person who says he or she is a genuine Christian, who can just walk away from the Lord, doesn't really know Jesus at all. They just know about Him. That haven't actually met Him yet.
