God pours down blessing…

Anyone, therefore, who shall with simplicity of heart direct his intention to God and free himself from all inordinate love or dislike for any creature will be most fit to receive grace and will be worthy of the gift of devotion. For where the Lord finds the vessel empty He pours down His blessing.
— Thomas à Kempis (1380-1471)

Discernment is needed…

How, then, should the person worthy of Christ’s great name behave? What can he do except to always discern his thoughts, words and deeds, and to see whether or not they are of Christ or are alien to him? Much skill is needed here for discernment. Anything effected, thought or said through passion has no association with Christ but bears the adversary’s mark; smearing the soul’s pearl with passion as if with mud, it corrupts the precious stone’s brightness. But a state free from every passion looks to the author of detachment, Christ. He who draws to himself thoughts as from a pure, incorruptible fountain will resemble the prototype as water drawn into a jar resembles water gushing from a fountain.
–Saint Gregory of Nyssa (c. 335 – c. 395)

Those who persevere…

The joys of this world lead to eternal sorrow; but those who persevere in following the joys that are to be found in the will of the Lord will find themselves led to an enduring, an eternal world.
— Ambrosiaster (Fourth Century)
