You know one of the primary problems with error is that it also breeds error especially within the same individual. This constant building of error upon error will eventually lead to full blown heresy if left unchecked. It is important for us all to go back time to time and inspect the foundation upon which we build to ensure our walls are true and our corners square. In my life I have found it most helpful to major upon the fundamentals of the faith as doing so has allowed me to steer a more straight course. "Lord make me strong enough to stand firmly for the Truth and humble enough to accept my brother's correction as a gift from you"
