The spiritual differs from the religious in being able to endure isolation. The rank of a spiritual person is proportionate to his strength for enduring isolation, whereas we religious people are constantly in need of 'the others,' the herd. We religious folks die, or despair, if we are not reassured by being in the assembly, of the same opinion as the congregation, and so on. But the Christianity of the New Testament is precisely related to the isolation of the spiritual man.
Soren KierkegaardImagine hidden in a simpler exterior a secret receptacle wherein the most precious treasure is deposited - there is a spring which has to be pressed, but the spring is hidden, and the pressure must have a certain strength, so that an accidental pressure would not be sufficient. So likewise is the hope of eternity hidden in man's inmost parts, and affliction is the pressure. When it presses the hidden spring, and strongly enough, then the contents appear in all their glory.
