St. Marcarius the Great

“Whatever the soul may think fit to do itself, whatever care and pains it may take, relying only upon its own power, and thinking to be able to effect a perfect success by itself, without the co-operation of the Spirit, it is greatly mistaken. It is of no use for the heavenly places; it is of no use for the kingdom – that soul, which supposes that it can achieve perfect purity of itself, and by itself alone, without the Spirit. Unless the man who is under the influence of the passions will come to God, denying the world, and will believe with patience and hope to receive a good thing foreign to his own nature, namely the power of the Holy Spirit, and unless the Lord shall drop upon the soul from on high the life of the Godhead, such a man will never experience true life, will never recover from the drunkenness of materialism; the enlightenment of the Spirit will never shine in that benighted soul, or kindle in it a holy daytime; it will never awake out of that deepest sleep of ignorance, and so come to know God of a truth through God’s power and the efficacy of grace.”
