Profound spiritual truth cannot simply be poured from one mind and heart to another.  It takes faith and diligent effort.  Precious truth comes a small piece at a time through faith, with great exertion, and at times wrenching struggles.  The Lord intends it to be that way so that we can mature and progress.
