And God saw all that he had done and, yes, it was very good. And there was evening and there was morning, the sixth day. — Genesis 1:31
This time it says very good but previously it said simply good, because now the components of faith combine with those of love to make one entity. A marriage between spiritual and heavenly things has taken place.
“Spiritual” is the adjective for anything having to do with religious knowledge. “Heavenly” applies to everything having to do with love for the Lord and for our neighbor. Spiritual things fall in the province of our intellect; heavenly things, in that of our will.
The periods and stages of our regeneration—both the whole process and individual cycles within it—divide into six, and these six are called our days of creation. Step by step we advance from being nonhuman to being somewhat human, though only a little, then more and more so up to the sixth day, when we become [God’s] image.
All the while the Lord is constantly fighting on our behalf against evil and falsity and through these battles strengthens us in truth and goodness. The time of conflict is when the Lord is at work (for which reason the prophets call a regenerate person the work of God’s fingers [Psalms 8:3, 6; Isaiah 19:25; 29:23; 45:11; 60:21; 64:8; Lamentations 4:2]), and he does not rest until love takes the lead. Then the conflict ends.
When the work progresses so far that faith is united with love, it is called very good, since the Lord now makes us likenesses of himself. At the end of the sixth day, evil spirits retreat and good ones take their place. We are led into heaven, or the Paradise of heaven.
