Spiritual life and perfection…

[S]piritual life and perfection… consists in nothing but coming near to God and union with Him, as was said in the beginning. With this is connected a heartfelt realization of the goodness and greatness of God, together with consciousness of our own nothingness and our proneness to every evil; love of God and dislike of ourselves; submission not only to God but also to all creatures, for the sake of our love of God; renunciation of all will of our own and perfect obedience to the will of God; and moreover desire for all this and its practice with a pure heart to the glory of God (I Corinthians 10:31), from sheer desire to please God and only because He Himself wishes it and because we should so love Him and work for Him.
–Saint Nikodemos the Hagiorite (1749-1809)
