Why is life a good? This question is found everywhere in the Bible, and from the very first pages it receives a powerful and amazing answer. The life which God gives man is quite different from the life of all other living creatures, inasmuch as man, although formed from the dust of the earth (cf. Gen 2:7, 3:19; Job 34:15; Ps 103:14; 104:29), is a manifestation of God in the world, a sign of his presence, a trace of his glory (cf. Gen 1:26-27; Ps 8:6). This is what Saint Irenaeus of Lyons wanted to emphasize in his celebrated definition: "Man, living man, is the glory of God".23 Man has been given a sublime dignity, based on the intimate bond which unites him to his Creator: in man there shines forth a reflection of God himself.
The Book of Genesis affirms this when, in the first account of creation, it places man at the summit of God's creative activity, as its crown, at the culmination of a process which leads from indistinct chaos to the most perfect of creatures. Everything in creation is ordered to man and everything is made subject to him: "Fill the earth and subdue it; and have dominion over ... every living thing" (1:28); this is God's command to the man and the woman. A similar message is found also in the other account of creation: "The Lord God took the man and put him in the garden of Eden to till it and keep it" (Gen 2:15). We see here a clear affirmation of the primacy of man over things; these are made subject to him and entrusted to his responsible care, whereas for no reason can he be made subject to other men and almost reduced to the level of a thing.
In the biblical narrative, the difference between man and other creatures is shown above all by the fact that only the creation of man is presented as the result of a special decision on the part of God, a deliberation to establish a particular and specific bond with the Creator: "Let us make man in our image, after our likeness" (Gen 1:26). The life which God offers to man is a gift by which God shares something of himself with his creature.
Israel would ponder at length the meaning of this particular bond between man and God. The Book of Sirach too recognizes that God, in creating human beings, "endowed them with strength like his own, and made them in his own image" (17:3). The biblical author sees as part of this image not only man's dominion over the world but also those spiritual faculties which are distinctively human, such as reason, discernment between good and evil, and free will: "He filled them with knowledge and understanding, and showed them good and evil" (Sir 17:7). The ability to attain truth and freedom are human prerogatives inasmuch as man is created in the image of his Creator, God who is true and just (cf. Dt 32:4). Man alone, among all visible creatures, is "capable of knowing and loving his Creator".24 The life which God bestows upon man is much more than mere existence in time. It is a drive towards fullness of life; it is the seed of an existence which transcends the very limits of time: "For God created man for incorruption, and made him in the image of his own eternity" (Wis 2:23).
35. The Yahwist account of creation expresses the same conviction. This ancient narrative speaks of a divine breath which is breathed into man so that he may come to life: "The Lord God formed man of dust from the ground, and breathed into his nostrils the breath of life; and man became a living being" (Gen 2:7).
The divine origin of this spirit of life explains the perennial dissatisfaction which man feels throughout his days on earth. Because he is made by God and bears within himself an indelible imprint of God, man is naturally drawn to God. When he heeds the deepest yearnings of the heart, every man must make his own the words of truth expressed by Saint Augustine: "You have made us for yourself, O Lord, and our hearts are restless until they rest in you".25
How very significant is the dissatisfaction which marks man's life in Eden as long as his sole point of reference is the world of plants and animals (cf. Gen 2:20). Only the appearance of the woman, a being who is flesh of his flesh and bone of his bones (cf. Gen 2:23), and in whom the spirit of God the Creator is also alive, can satisfy the need for interpersonal dialogue, so vital for human existence. In the other, whether man or woman, there is a reflection of God himself, the definitive goal and fulfilment of every person.
"What is man that you are mindful of him, and the son of man that you care for him?", the Psalmist wonders (Ps 8:4). Compared to the immensity of the universe, man is very small, and yet this very contrast reveals his greatness: "You have made him little less than a god, and crown him with glory and honour" (Ps 8:5). The glory of God shines on the face of man. In man the Creator finds his rest, as Saint Ambrose comments with a sense of awe: "The sixth day is finished and the creation of the world ends with the formation of that masterpiece which is man, who exercises dominion over all living creatures and is as it were the crown of the universe and the supreme beauty of every created being. Truly we should maintain a reverential silence, since the Lord rested from every work he had undertaken in the world. He rested then in the depths of man, he rested in man's mind and in his thought; after all, he had created man endowed with reason, capable of imitating him, of emulating his virtue, of hungering for heavenly graces. In these his gifts God reposes, who has said: ?Upon whom shall I rest, if not upon the one who is humble, contrite in spirit and trembles at my word?' (Is 66:1-2). I thank the Lord our God who has created so wonderful a work in which to take his rest".26
36. Unfortunately, God's marvellous plan was marred by the appearance of sin in history. Through sin, man rebels against his Creator and ends up by worshipping creatures: "They exchanged the truth about God for a lie and worshipped and served the creature rather than the Creator" (Rom 1:25). As a result man not only deforms the image of God in his own person, but is tempted to offences against it in others as well, replacing relationships of communion by attitudes of distrust, indifference, hostility and even murderous hatred. When God is not acknowledged as God, the profound meaning of man is betrayed and communion between people is compromised.
In the life of man, God's image shines forth anew and is again revealed in all its fullness at the coming of the Son of God in human flesh. "Christ is the image of the invisible God" (Col 1:15), he "reflects the glory of God and bears the very stamp of his nature" (Heb 1:3). He is the perfect image of the Father.
The plan of life given to the first Adam finds at last its fulfilment in Christ. Whereas the disobedience of Adam had ruined and marred God's plan for human life and introduced death into the world, the redemptive obedience of Christ is the source of grace poured out upon the human race, opening wide to everyone the gates of the kingdom of life (cf. Rom 5:12-21). As the Apostle Paul states: "The first man Adam became a living being; the last Adam became a life-giving spirit" (1 Cor 15:45).
All who commit themselves to following Christ are given the fullness of life: the divine image is restored, renewed and brought to perfection in them. God's plan for human beings is this, that they should "be conformed to the image of his Son" (Rom 8:29). Only thus, in the splendour of this image, can man be freed from the slavery of idolatry, rebuild lost fellowship and rediscover his true identity.
