Life As A Christian Is All About Growth. Faith Saves Us then Comes Sanctification then Glorification. For Churches to condemn people for not being spiritual enough is the wrong thing to do. There are Carnal Christians - and Baby Christians Both move to maturity and it may take time. Or they May Never Grow but they are still Christians.
We Fight An Invisible yet Noticeable battle with Spirit World, in fact according to The bible the spirits live in us - thats why it's necessary to have a new spirit in you.
