...the souls of the dead [are] not deprived of their intellectual faculties but... they also are not lacking in feelings such as hope and sadness, joy and fear. They already have a foretaste of what is in store for them after the general judgment. Nor does it happen, as some unbelievers would hold, that upon leaving this world they are turned to nothing. Actually they live more intensely and they concentrate more on the praises of God.
John CassianMen seized of the urge to have a knowledge of God and to be pure in mind devote all their gathered energies to this one task. While they still live in the corruption of the flesh they give themselves to that service in which they will persevere when the corruption has been laid aside. And already they come in sight of what the Lord and Savior held out when He said, 'Blessed are the clean of heart, for they will see God' (Mt. 5:8).

John CassianGod is not only to be known in His blessed and incomprehensible being, for this is something which is reserved for His saints in the age to come. He is also known from the grandeur and beauty of His creatures, from His providence which governs the world day by day, from His righteousness and from wonders which He shows to His saints in each generation.
