shall never hunger, and he who believes in Me shall never thirst.”
The Law of Life says that the presence of Christ within the believer results in spiritual satisfaction. If we have Him then we will never hunger or thirst again, because He is Infinite Supply.
Anything less than spiritual satisfaction indicates that there is a problem. I am not saying that one should be content with their progress and present knowledge of Christ so that they stop growing; but I am saying that no matter what stage of progress you may be at presently, Christ should be your satisfaction.
