There's a big difference between having a relationship with God and being saved. Anyone, any where, any time can be saved by simply accepting Christ. Anyone who has done so is going to heaven, no matter what. Having a relationship is a way of life, not a way of salvation. It allows you to have a few of the benefits of salvation here on earth but doesn't affect whether you're actually saved or not. You can live alone in the most remote place on earth for years, totally separated from any Christians, and still be saved. Having a relationship there though, is far more difficult.
