Without the church it's like having a boat without the rudder. You think you can do it on your own and this may sound pedestrian or trite but I'll equate it to this: all my life I've been involved with exercise but no matter how much - and I know a great deal about the body - you need help. You need a trainer. You need to go to a gym and you need to have the expertise and the guidance of someone else. You cannot train yourself. I feel the same way about Christianity and what the church is. The church is the gym of the soul.
