You can't remain a Christian after leaving the WT, because you have never been one.
I left a man-made organisation, not God. I still had the desire to worship God, even after nearly 30 years as a JW. Not because they had got me that way , but because I did feel a need to worship.
On trying to find somewhere I soon discovered that there are lots of small groups who meet on fellowship as Christians. Like minded people who have set up their own fellowship. Usually mainly people from the Church of England and the Roman Catholic church, who had felt that those churches were losing their way and had turned aside from Christian teachings.
I ended up attending a Pentecostal church. Why? Because I felt that God was there. They believe implicity in the Bible and only use it, no magazines books etc telling you what to believe. I suppose the biggest thing was that I'm able to discuss with members your views without fear of being considered "apsotate" and bing kicked out. The Pastor is a great speaker and makes the word of God alive. But you can go to him and say you don't agree with him or as had happen point out he was wrong on something. Then he will get up next Sunday and admit he had got it wrong. It is similar within the Bible classes they hold, or at the housegroups. You can discuss your beliefs and not be afraid someone will run off and tell an Elder. My son (28) also an ex-JW also now attends, when a JW he would never speak about God etc, unless he had to, at meeetings or field service etc. He has been attending for about 2 years now, and you can't shut him up for wanting to discuss Christ.
I've been attending for 3 years now and have seen more love in action than I did in all the years as a JW. Towards me and to others, even those not of the church. A couple of years ago a man who lived locally to the church, was murdered in the street close by. That next Sunday afterwards the Pastor asked if we could give that mornings tithes and offerings to the mans family, as they would be facing some hardship. We raised about £500 and he took it round the next day. That family had no connection whatsoever with the church. This and similar ones shows Christian love in action, compared to the JW version.
The church is very evangelistic, and has even a program of calling on people homes!! They have a good youth program, clubs on Saturday morning and evening, open to all youths in the area.
I'm not saying everything they do is right or wrong or perfect, they even admit that themselves, but the freedom of it is refreshing after the JW's.
