Peace is defined as harmony among those who are divided. When, therefore, we end the civil war within our nature and cultivate peace within ourselves, we become at peace.
Gregory of NyssaMore Gregory of Nyssa quotes
Our Lord says, to those who can hear what Wisdom speaks beneath a mystery, that "the Kingdom of God is within you" (Luke 17:21). That word points out the fact that the Divine good is not something apart from our nature, and is not removed far away from those who have the will to seek it; it is in fact within each of us, ignored indeed, and unnoticed while it is stifled beneath the cares and pleasures of life, but found again whenever we can turn our power of conscious thinking towards it.
Gregory of Nyssa
Evil will come to nought and will be completely destroyed. The divine, pure goodness will contain in itself every nature endowed with reason; nothing made by God is excluded from his kingdom once everything mixed with some elements of base material has been consumed by refinement in fire.
Gregory of Nyssa
Sick, our nature demanded to be healed; fallen, to be raised up; dead, to rise again... Closed in the darkness, it was necessary to bring us the light; captives, we awaited a Savior... Are these things minor or insignificant? Did they not move God to descend to human nature and visit it, since humanity was in so miserable and unhappy a state?
Gregory of Nyssa
