Let us consider then how rich in its wealth is the ocean of His creative act, and how many created things belong to God, and how in His compassion He carries everything, acting providentially as He guides creation;
and how with a love that cannot be measured He arrived at the establishment of the world and the beginning of creation; and how compassionate God is, and how patient;
and how He loves creation, and how He carries it, gently enduring its importunity, the various sins and wickednesses, the terrible blasphemies of demons and evil men.
Then, once someone has stood amazed, and filled his intellect with the majesty of God, amazed at all these things He has done and is doing, then he wonders in astonishment at His mercifulness,
how, after all these things, God has prepared for them another world that has no end, whose glory is not even revealed to the angels, even though they are involved in His activities insofar as is possible in the life of the spirit, in accordance with the gift with which their nature has been endowed.
That person wonders too at how excelling is that glory, and how exalted is the manner of existence at that time; and how insignificant is the present life compared to what is reserved for creation in the New Life;
and how, in order that the soul’s life will not be deprived of that blessed state because of misusing the freewill it has received, He has devised in His mercifulness a second gift, which is repentance, so that by it the soul’s life might acquire renewal every day and thereby every time be put aright (II.10.19).
[…] What profundity of richness, what mind and exalted wisdom is God’s! What compassionate kindness and abundant goodness belongs to the Creator! With what purpose and with what love did He create this world and bring it into existence!
What a mystery does the coming into being of this creation look towards! To what a state is our common nature invited! What love served to initiate the creation of the world!
This same love which initiated the act of creation prepared beforehand by another dispensation the things appropriate to adorn the world’s majesty which sprung forth as a result of the might of His love.
In love did He bring the world into existence; in love does He guide it during this its temporal existence; in love is He going to bring it to that wondrous transformed state, and in love will the world be swallowed up in the great mystery of Him who has performed all these things; in love will the whole course of the governance of creation be finally comprised (II.38.1-2).
