If you ask, my brother, why you do not see things that are to come, or observe hidden things, or speak wonders, or understand glorious mysteries, then hear me, my brother, and I will tell you the reason you are cut off from these benefits.
Truly, my beloved, there is no logical mind that is not appointed to be the seer of all things that have been and shall be, unless it is blind in the things that are seen. There is no human heart that would not be a fountain of the mysteries hidden in the bosom of the Father, if its courses were not blocked up by the mud of the passions.
There is no tongue of any man in the image of God that would not be speaking the wonders of God and revealing his hidden mysteries, if it were not stuttering from the cold of evil. There is no soul that would not bear Christ in its bosom, if it had not become depraved with its enemies through its laxity.
Nevertheless, repentance causes us to be born again in the image of God and restores all these things to us. Blessed is the giver of repentance, who grants it to us for the revival of our deadness. To him be glory for ever and ever. Amen.
[John of Dalyatha, DiscourseĀ 14]
