Is your faith and Christianity the real deal, actually letting teachings of Jesus lead you, and the Spirit which comes with them, or just lip service? Is it just part of mass conversion perhaps long ago in history, where you did not even get to decide, just trying not to rebel? How to tell? It is a community thing. When you meet with others like yourself in a service, is it something which is truly in the name of Jesus Christ, and is the Spirit of Christ clearly there with you? That is the test.
