Do not be troubled if you do not immediately receive from God what you ask Him; for He desires to do something even greater for you, while you cling to Him in prayer.
Evagrius PonticusThe Holy Spirit, out of compassion for our weakness, comes to us even when we are impure. And if He finds our intellect truly praying to Him, He enters it and puts to flight the whole array of thoughts and ideas circling within it, and He arouses it to a longing for spiritual prayer.
Evagrius Ponticus
