Gen 1, 4-5 God saw how good the light was

(Gen 1, 4-5) God saw how good the light was

[4] God saw how good the light was. God then separated the light from the darkness. [5] God called the light "day," and the darkness he called "night." Thus evening came, and morning followed - the first day.

(CCC 299) Because God creates through wisdom, his creation is ordered: "You have arranged all things by measure and number and weight" (Wis 11:20). The universe, created in and by the eternal Word, the "image of the invisible God", is destined for and addressed to man, himself created in the "image of God" and called to a personal relationship with God (Col 1:15, Gen 1:26). Our human understanding, which shares in the light of the divine intellect, can understand what God tells us by means of his creation, though not without great effort and only in a spirit of humility and respect before the Creator and his work (Cf. Ps 19:2-5; Job 42:3). Because creation comes forth from God's goodness, it shares in that goodness - "and God saw that it was good… very good" (Gen 1:4, 10, 12, 18, 21, 31) - for God willed creation as a gift addressed to man, an inheritance destined for and entrusted to him. On many occasions the Church has had to defend the goodness of creation, including that of the physical world (Cf. DS 286; 455-463; 800; 1333; 3002). (CCC 283) The question about the origins of the world and of man has been the object of many scientific studies which have splendidly enriched our knowledge of the age and dimensions of the cosmos, the development of life-forms and the appearance of man. These discoveries invite us to even greater admiration for the greatness of the Creator, prompting us to give him thanks for all his works and for the understanding and wisdom he gives to scholars and researchers. With Solomon they can say: "It is he who gave me unerring knowledge of what exists, to know the structure of the world and the activity of the elements… for wisdom, the fashioner of all things, taught me" (Wis 7: 17-22).
