The abode and resting place of the Holy Spirit is humility, love, gentleness and the other holy commandments of Christ. If, therefore, a person desires to grow and to attain perfection by acquiring all these virtues, he must initially force himself to acquire and must establish himself in the first–that is to say, in prayer–wrestling and striving with his heart to make it receptive and obedient to god.
~St Makarios of Egypt
