Hi Trumind: Most organized religions do not teach that you need to belong to them to be saved (or "approved" by God as the JWs say). The vast majority of Christians recognize that organizations is simply for convenience, and has absolutely no bearing on your relationship with God.
Jesus promised that where two or more are gathered in his name, there he would be. So, any Christian may gather anywhere, anytime whether in a church or other place, and Jesus is present.
The Watchtower teaches that if we work real hard, and do all they tell us, we might get God's 'approval' --- maybe, maybe not.
Jesus Christ taught us that we are loved by God as his children. In fact if you carefully read John, Chap 17 you will see that Jesus states we are loved by God 'already' as much as he loves Jesus Christ.
Nowherer in the Bible is anything said about being a member of any group or organized church. Rather, Jesus said that he is the way, the truth, and the life. So, if you remain Christian, then Jesus Christ is the only one you need to go to for a relationship with God ... a relationship already approved at the highest level ... because Jesus paid for that relationship, and not some organization.
